…ing Flow Graph instances Added a new FlowCacheService for in-memory caching of Flow Graph instances to enhance performance. Introduced FlowCacheServiceFactory for creating instances of FlowCacheService. This implementation includes methods for adding, removing, and retrieving cached graphs, with appropriate logging for error handling and debugging.
Introduced a new asynchronous function, get_flow_by_id_or_endpoint_name_from_cache, to enhance flow retrieval by utilizing the FlowCacheService. This function checks for cached flows and raises a 404 error if not found, improving performance and user experience when accessing flow data.
…enum Implemented the get_flow_cache_service function to retrieve the FlowCacheService instance from the service manager. Updated the ServiceType enum to include FLOW_CACHE_SERVICE, enhancing the service management capabilities for flow caching.
Updated the update_flow function to integrate FlowCacheService for managing flow caching. Added background tasks to handle flow addition and removal from the cache based on deployment state, improving performance and state management during flow updates.
…w retrieval Modified the simple_run_flow and simplified_run_flow functions to accept Graph instances alongside Flow objects. Updated the flow dependency in simplified_run_flow to utilize the new get_flow_by_id_or_endpoint_name_from_cache function, enhancing flow retrieval with caching support. This change improves flexibility and performance in handling flow data.

…tion Updated the assignment of the custom_component in the Vertex class to ensure proper instantiation. This change enhances the clarity and correctness of component initialization, contributing to more robust component management.
…om_cache function Changed the default value of the use_cache parameter in the get_flow_by_id_or_endpoint_name_from_cache function from True to False. This adjustment improves the function's behavior by preventing unintended cache usage, enhancing the robustness of flow retrieval.

Implemented the handleDeployedSwitch function to manage the deployment status of flows asynchronously. This includes updating the flow state on success and handling errors gracefully. Enhanced the UI to reflect the deployed status with appropriate tooltips and switch functionality.
Modified the Alembic migration script to correctly reference the new deployment state enum for the status column in the flow table. Adjusted the down_revision identifier and improved type hints for better clarity. Ensured the deployment state enum is created and dropped appropriately during the upgrade and downgrade processes.
Cleaned up the endpoints.py file by removing unnecessary imports related to Graph and RunOutputs, enhancing code clarity and maintainability.

5-14: LGTM! Singleton pattern already implemented.The factory correctly implements the singleton pattern by caching the FlowCacheService instance and reusing it on subsequent calls, which is exactly what the past review comment suggested.
Note: The codeflash-ai optimization suggestion from a previous review has already been addressed by this implementation.
🧹 Nitpick comments (11)
src/lfx/tests/unit/services/cache/test_cache_miss.py (1)
55-62: Reconsider the!= Nonecomparison for consistency.Line 58 uses
!= Nonewith a noqa comment to suppress the linter warning. While this explicitly tests the!=operator behavior, it's inconsistent with Python best practices. Unless there's a specific reason to verify!=operator behavior (e.g., ifCacheMissimplements__ne__), preferis not Nonefor clarity and consistency.Apply this diff if no specific need to test
!=operator:- assert CACHE_MISS != None # noqa: E711 + assert CACHE_MISS is not Nonesrc/frontend/tests/core/features/deploy-flow.spec.ts (2)
5-95: Add test coverage for error scenarios and edge cases.The test suite covers happy paths but misses important error and edge cases that could occur during deployment operations.
Consider adding tests for:
- Deployment failure handling: What happens if the backend deployment fails?
- Network interruption: Test behavior when deployment API call is interrupted
- Permission errors: Test unauthorized deployment attempts
- Concurrent modifications: Test race conditions if flow is modified during deployment
- Stale state recovery: Test UI recovery if deployment state becomes inconsistent
Example test structure:
test( "deployment failure shows error message", { tag: ["@release", "@workspace", "@api"] }, async ({ page }) => { await awaitBootstrapTest(page); await page.getByTestId("blank-flow").click(); // Mock deployment API to return error await page.route('**/api/v1/flows/*/deploy', route => route.fulfill({ status: 500, body: 'Deployment failed' }) ); await page.getByTestId("publish-button").click(); await page.getByTestId("deploy-switch").click(); // Verify error message is displayed await expect(page.getByRole('alert')).toContainText('Deployment failed'); // Verify switch reverts to unchecked state await expect(page.getByTestId("deploy-switch")).toBeChecked({ checked: false }); } );As per coding guidelines: "Test error handling and edge cases in frontend test files."
Also applies to: 97-166, 168-199, 201-277
51-60: Consider removing or simplifying the try-catch block.The try-catch logs the error but immediately rethrows it, which doesn't add value in test execution. Playwright's built-in error messages are already descriptive.
Either remove the try-catch entirely:
-try { - await page.waitForTimeout(2000); - - await expect(page.getByTestId("deploy-switch")).toBeVisible({ - timeout: 10000, - }); -} catch (error) { - console.error("Error waiting for deploy operation:", error); - throw error; -} +await expect(page.getByTestId("deploy-switch")).toBeVisible({ + timeout: 10000, +});Or add meaningful recovery/diagnostic logic:
try { - await page.waitForTimeout(2000); - await expect(page.getByTestId("deploy-switch")).toBeVisible({ timeout: 10000, }); } catch (error) { - console.error("Error waiting for deploy operation:", error); + // Capture screenshot for debugging + await page.screenshot({ path: 'deploy-switch-failure.png' }); + console.error("Deploy switch not visible. Current page state:", { + url: page.url(), + dropdownOpen: await page.getByTestId("publish-button").isVisible(), + }); throw error; }src/backend/base/langflow/api/v1/schemas.py (1)
447-447: Consider strengthening the type annotation.The
statusfield is typed asstr | Nonebut the comment indicates onlyDRAFTorDEPLOYEDare valid values. Consider using aLiteraltype for better type safety and automatic validation:- status: str | None = None # DRAFT or DEPLOYED + status: Literal["DRAFT", "DEPLOYED"] | None = NoneDon't forget to add
Literalto the imports fromtypingat the top of the file if it's not already imported.src/frontend/src/components/core/flowToolbarComponent/components/__tests__/deploy-dropdown.test.tsx (3)
367-384: Test doesn’t assert tooltip contentThe test name mentions tooltip content, but it only checks presence of the menu item. Assert the actual tooltip text after hover/focus.
Example:
- await waitFor(() => { - const deployedStatus = screen.getByTestId("deployed-status"); - expect(deployedStatus).toBeInTheDocument(); - }); + const deployedStatus = await screen.findByTestId("deployed-status"); + await user.hover(deployedStatus); + expect(await screen.findByText(/Deploy to make this flow available via API/i)).toBeInTheDocument();
1-3: Unused importfireEvent is imported but unused; lint will flag it.
118-141: Add coverage for publish switch toggling (potential bug)There’s no test for the publish switch. In deploy-dropdown.tsx, handlePublishedSwitch receives the current isPublished value (not toggled), which likely flips logic. Add a test that toggles publish and asserts mutateAsync is called with PUBLIC/PRIVATE as expected.

44-49: user_id type to Graph.from_payloadGraph.from_payload likely expects str for user_id (simple_run_flow uses str(user_id)). Pass str to avoid type inconsistencies.
Apply:
- graph = Graph.from_payload(graph_data, flow_id=flow_id_str, user_id=flow.user_id, flow_name=flow.name) + graph = Graph.from_payload( + graph_data, flow_id=flow_id_str, user_id=str(flow.user_id) if flow.user_id else None, flow_name=flow.name + )
123-178: get_cache_stats OK but heavy; consider delegating endpoint to this methodPrefer using this locked method from API endpoints (/cache) rather than reimplementing stats in endpoints.py.
src/backend/base/langflow/api/v1/flows.py (1)
367-375: Endpoint name change leaves old alias cachedWhen DEPLOYED and endpoint_name changes, refresh_flow_in_cache adds the new alias but remove_flow_from_cache doesn’t clear the old alias; stale key remains.
Consider tracking aliases per flow in FlowCacheService (id→set of keys) to remove previous endpoint aliases on refresh. Based on learnings
src/backend/base/langflow/api/v1/endpoints.py (1)
404-406: CACHE_MISS check here is redundantget_flow_by_id_or_endpoint_name_from_cache returns Graph or Flow object; sentinel won’t escape. You can simplify to “if flow is None”.

5-7: Confirm lfx workspace dependency and API compatibility
pyproject.toml already includes lfx as a workspace package. Verify that the external Graph, layered_topological_sort, and Vertex APIs remain compatible with their previous internal implementations (e.g., Graph.from_payload, Vertex.build) to prevent runtime errors.src/lfx/tests/unit/services/cache/test_cache_miss.py (1)
1-94: Comprehensive test coverage for sentinel behavior.The test suite thoroughly validates
CacheMissbehavior across common Python patterns:
- Boolean evaluation and control flow (if, if not, ternary)
- Identity checks and None distinction
- String representations
- Practical usage patterns (or defaults, list comprehension filtering)
The tests are well-structured, follow pytest conventions, and validate actual behavior rather than being mere smoke tests. Good work on covering edge cases and multiple interaction scenarios.

1-3: LGTM! Test structure and organization are solid.The test file follows good practices:
- Clear test descriptions with appropriate tags
- Proper use of shared utilities (

src/frontend/src/modals/apiModal/index.tsx (2)
56-60: LGTM!The deployment status check is correctly implemented, comparing against
DEPLOYMENT_STATUS.DEPLOYED. The logic properly defaults to not deployed when the status is undefined.
162-180: LGTM!The deployment warning banner provides clear, actionable feedback to users when a flow is not deployed. The non-blocking approach (warning instead of preventing access) is appropriate, allowing users to view API details while being informed about the deployment requirement.

812-812: LGTM! Proper placement of component reset.Calling
_reset_components_in_vertices()after assembling vertex outputs (line 811) is the correct location, ensuring components are cleaned up after the run completes but before returning results.src/backend/base/langflow/services/deps.py (1)

72-72: LGTM! Component class tracking added.The implementation properly captures and stores the component class object during instantiation, enabling components to be traced back to their class definitions for caching and reconstruction purposes.
Also applies to: 380-383, 404-409
385-386: Verify if class object should also be reset.The
reset_componentmethod clearscustom_componentbut leaves_custom_component_classintact. Ensure this is intentional—if the class object should be preserved for component reconstruction, this is correct. Otherwise, consider also settingself._custom_component_class = None.src/backend/base/langflow/api/v1/mcp_projects.py (1)
222-227: LGTM! Clear documentation and status field integration.The comments effectively clarify that all flows are accessible via MCP regardless of deployment status, with deployed flows benefiting from caching. The status field addition properly exposes deployment state to the frontend.
Also applies to: 256-256
src/frontend/src/pages/FlowPage/components/PageComponent/MemoizedComponents.tsx (2)
38-61: LGTM! Proper state management with cleanup.The status display effects correctly show text briefly when state changes and properly clean up timers to prevent memory leaks.
65-92: LGTM! Polished status indicators with smooth transitions.The deployment and lock status buttons provide clear visual feedback with smooth CSS transitions, proper hover states, and accessibility attributes.
Also applies to: 98-119

Use an outer join so folder-less orphaned flows are reassigned.
Switching to an inner join(models.Folder) means any orphaned flow without a folder (i.e., folder_id is NULL—the common case) no longer appears in orphaned_flows, so we silently skip reassigning exactly the flows we’re supposed to fix. Please revert to an outer join (or add an or_(Folder.name.is_(None)) guard) so folderless flows remain eligible while still excluding the starter folder.

Add actual lock verification logic.
The test claims "deployed flows should be locked" but only verifies that the Chat Input node is visible. It doesn't actually test whether the flow is locked or attempt any edit operations to verify lock enforcement.
Add assertions that verify lock behavior:
// Try to edit - flow should be locked
-// Check if lock indicator is visible (assuming there's a lock icon or similar)
-await page.waitForTimeout(1000);
+// Verify lock indicator is visible

the test only checks visibility of the Chat Input node but does not verify the

lock indicator element or a UI state class (e.g. data-testid or CSS class

Misleading test name contradicts actual behavior.
The test name test_cache_miss_singleton_pattern implies that CACHE_MISS follows the singleton pattern, but the test explicitly verifies that new_instance is not CACHE_MISS, demonstrating that multiple distinct instances can be created. This contradicts singleton behavior, where only one instance should exist.
The test is actually validating that multiple CacheMiss instances share the same behavioral characteristics (falsy evaluation, repr), not singleton identity.
Choose one of the following solutions:
Option 1 (rename test): Rename to reflect what's actually being tested:

- """Test that CACHE_MISS is a singleton."""
- # Creating a new instance should give us a different object
- # but CACHE_MISS itself should be the same everywhere

+ """Test that multiple CacheMiss instances have consistent behavior."""
+ # Creating a new instance gives a different object
+ # but all instances share the same falsy behavior and reprOption 2 (enforce singleton): If singleton behavior is desired, implement it in the CacheMiss class (using __new__ to return the same instance) and update the test assertions accordingly:
new_instance = CacheMiss()
- assert new_instance is not CACHE_MISS # Different instances

146-197: CachedGraphobjects trigger crashes
simplified_run_flownow injects cachedGraphinstances, butsimple_run_flowstill assumes it received a ORMFlow(flow.data,flow.name, copy of dict, reparse viaGraph.from_payload). With a cached graph we hitAttributeErrorimmediately. Guard onisinstance(flow, Graph)(reuse the object, pick up metadata likeflow.flow_id,flow.flow_name) and only rebuild when you’re handed aFlow/FlowRead. Without that branch, every cache hit breaks the run path.Suggested shape:
- flow_id_str = str(flow.id) - if flow.data is None: - ... - graph_data = flow.data.copy() - graph_data = process_tweaks(...) - graph = Graph.from_payload(...) + if isinstance(flow, Graph): + graph = deepcopy(flow) + flow_id_str = getattr(flow, "flow_id", None) or getattr(flow, "id") + flow_name = getattr(flow, "flow_name", None) + else: + flow_id_str = str(flow.id) + if flow.data is None: + ... + graph_data = flow.data.copy() + graph_data = process_tweaks(...) + graph = Graph.from_payload( + graph_data, + flow_id=flow_id_str, + user_id=str(user_id), + flow_name=flow.name, + context=context, + ) + flow_name = flow.nameThen use

Consider updating to:def instantiate_class( vertex: Vertex, user_id=None, event_manager: EventManager | None = None, ) -> tuple[CustomComponent | Component, dict, type[CustomComponent | Component]]:This improves type safety and makes the return structure explicit.

10-40: Consider reducing mock complexity or adding integration tests.The test setup includes extensive mocking of UI components (Sidebar, TableComponent), which obscures what's actually being tested. The current tests only verify that the component doesn't crash on render, not that the deployment toggle behavior works correctly.
Consider:
- Testing the actual deployment toggle interaction using
userEvent- Verifying that
mockMutateAsyncis called with correct arguments- Adding integration tests that use real components instead of mocks for the core behavior
As per coding guidelines: Excessive mocks that replace core logic reduce test value. Consider integration tests when unit tests become overly mocked.

src/backend/tests/**/*.py: Unit tests for backend code must be located in the 'src/backend/tests/' directory, with component tests organized by component subdirectory under 'src/backend/tests/unit/components/'.
Test files should use the same filename as the component under test, with an appropriate test prefix or suffix (e.g., 'my_component.py' → 'test_my_component.py').
Use the 'client' fixture (an async httpx.AsyncClient) for API tests in backend Python tests, as defined in 'src/backend/tests/conftest.py'.
When writing component tests, inherit from the appropriate base class in 'src/backend/tests/base.py' (ComponentTestBase, ComponentTestBaseWithClient, or ComponentTestBaseWithoutClient) and provide the required fixtures: 'component_class', 'default_kwargs', and 'file_names_mapping'.
Each test in backend Python test files should have a clear docstring explaining its purpose, and complex setups or mocks should be well-commented.
Test both sync and async code paths in backend Python tests, using '@pytest.mark.asyncio' for async tests.
Mock external dependencies appropriately in backend Python tests to isolate unit tests from external services.
Test error handling and edge cases in backend Python tests, including using 'pytest.raises' and asserting error messages.
Validate input/output behavior and test component initialization and configuration in backend Python tests.
Use the 'no_blockbuster' pytest marker to skip the blockbuster plugin in tests when necessary.
Be aware of ContextVar propagation in async tests; test both direct event loop execution and 'asyncio.to_thread' scenarios to ensure proper context isolation.
Test error handling by mocking internal functions using monkeypatch in backend Python tests.
Test resource cleanup in backend Python tests by using fixtures that ensure proper initialization and cleanup of resources.
Test timeout and performance constraints in backend Python tests using 'asyncio.wait_for' and timing assertions.

src/backend/base/langflow/services/schema.py (1)
22-22: LGTM!The enum addition follows the existing naming pattern and integrates cleanly with the service infrastructure.
src/backend/base/langflow/api/v1/mcp_utils.py (2)
195-199: LGTM! Good defensive coding with clear fallback behavior.The implementation correctly attempts to use the cached graph for better performance while gracefully falling back to the database flow when the cache is unavailable. The inline comments clearly explain the behavior.
240-240: LGTM! Correct usage of cached flow.The flow execution correctly uses
flow_to_run, which will be either the cached graph or the original database flow depending on cache availability.src/frontend/src/controllers/API/queries/flows/use-patch-update-flow.ts (1)
17-17: LGTM! Proper use of TypeScript literal types.The status field correctly uses a literal union type (
"DRAFT" | "DEPLOYED"), providing compile-time type safety and preventing invalid values.src/frontend/src/hooks/flows/use-save-flow.ts (1)
72-72: LGTM! Status field correctly preserved during save.The implementation correctly destructures the
statusfield from the flow object and includes it in the mutation payload, ensuring deployment state is preserved when saving flows.Also applies to: 84-84
src/frontend/src/types/flow/index.ts (1)
36-36: LGTM! Proper TypeScript type definition.The status field correctly uses a literal union type, providing compile-time type safety consistent with the rest of the FlowType definition.
src/frontend/src/types/mcp/index.ts (1)
23-23: LGTM! Proper TypeScript type definition.The status field correctly uses a literal union type (
"DRAFT" | "DEPLOYED"), providing compile-time type safety and maintaining consistency with other type definitions in the codebase.src/backend/base/langflow/services/socket/utils.py (1)
5-7: LGTM! Import path updates align with package reorganization.The imports have been updated to reflect the new package structure (lfx.graph.*), and all imported symbols are properly used in the file. The move of
log_vertex_buildto the.crudsubmodule provides better organization.Also applies to: 14-14
src/frontend/src/modals/apiModal/index.tsx (1)
162-180: LGTM! Clear deployment warning enhances user experience.The warning panel provides clear feedback when a flow is not deployed, with an actionable message directing users to the Share menu. The UI structure and styling are consistent with the codebase.
src/backend/base/langflow/alembic/versions/ea8c52f13171_add_status_column_in_flow.py (2)
23-34: LGTM! Migration is idempotent and safe.The migration properly uses:
checkfirst=Trueto avoid duplicate enum creationcolumn_existscheck to prevent duplicate column addition- Correct
server_defaultsyntax with quoted string for enum valuenullable=Falsewith a default valueThese safeguards make the migration safe for re-running.
37-46: LGTM! Downgrade path is safe and complete.The downgrade properly:
- Checks column existence before dropping
- Drops the enum type with
checkfirst=True- Correctly reverses all changes from the upgrade
src/backend/tests/unit/api/v1/test_mcp_projects.py (4)
518-518: LGTM! Pragma comments correctly suppress false positives.The
pragma: allowlist secretmarkers are appropriately placed on test secret values to prevent security scanners from flagging them as issues.Also applies to: 567-567
730-783: LGTM! Test ensures backward compatibility.This test validates that both DRAFT and DEPLOYED flows are accessible via MCP, confirming no breaking changes were introduced. The test aligns with the documented behavior that deployment is for caching optimization, not access control.
785-835: LGTM! Test validates state transitions correctly.This test effectively verifies that the status field in MCP tools accurately reflects the flow's deployment state, including state transitions from DRAFT to DEPLOYED. The assertions are clear and comprehensive.
685-727: Confirm database cleanup strategyThe test correctly validates that deployment status is exposed via
list_project_tools, but it commits real DB records without explicit teardown. Confirm that your test suite resets or isolates the database between tests to avoid data pollution.src/backend/base/langflow/services/flow_cache/factory.py (1)
5-14: LGTM! Singleton pattern appropriate for cache service.The singleton implementation is correct for a cache service that should be shared across the application. The FlowCacheService itself has internal async locking for cache operations (from
AsyncInMemoryCache), which provides the necessary concurrency safety.Based on learnings: The optimization provides a 43% speedup by avoiding repeated instantiation of the FlowCacheService.
src/backend/base/langflow/api/v1/mcp_projects.py (2)
222-227: LGTM! Helpful comment clarifies deployment behavior.The query reformatting improves readability, and the comment clearly documents that:
- All flows are accessible via MCP regardless of deployment status
- Deployed flows benefit from caching for performance
This aligns with the test coverage in
test_mcp_projects.pythat verifies both DRAFT and DEPLOYED flows are included.
248-257: MCPSettings schema correctly includes the status fieldThe
statusattribute is defined onMCPSettings(str | None), sostatus=flow.statusis accepted.src/lfx/src/lfx/interface/initialize/loading.py (1)
54-54: All instantiate_class call sites correctly unpack three values. No further changes needed.src/backend/base/langflow/services/deps.py (1)
247-251: Flow cache accessor LGTMFactory-based accessor matches existing patterns and ServiceType. No issues.
src/lfx/tests/unit/services/cache/test_cache_miss.py (1)
1-94: Solid sentinel behavior coverageCovers truthiness, identity, repr, control-flow, and list filtering. Looks good.
src/backend/base/langflow/services/database/models/flow/model.py (1)
74-86: Naming risk: status field may collide with existing frontend usageBackend status holds deployment state, but some UI paths (e.g., ToolsTable) already use status as a boolean for selection. This leads to breakage/confusion. Consider either:
- Renaming the API field to deployment_status (with alias="status" if keeping wire format), or
- Coordinating FE to use a distinct selected flag and a separate deploymentStatus field.
Please verify all FE and API consumers are updated accordingly; the current UI shows a concrete collision.
src/backend/base/langflow/services/utils.py (1)
302-307: Old endpoint aliases remain cached after updates
Right beforerefresh_flow_in_cache/remove_flow_from_cacheyou overwritedb_flow.endpoint_name. When the endpoint changes, the cache eviction only sees the new name, so the previous endpoint key stays live and still returns the old graph. Capture the prior endpoint value and pass it (see proposedextra_keys) so both old and new aliases are purged.Example:
- for key, value in update_data.items(): - setattr(db_flow, key, value) + previous_endpoint = db_flow.endpoint_name + for key, value in update_data.items(): + setattr(db_flow, key, value) ... - await flow_cache_service.refresh_flow_in_cache(db_flow) + await flow_cache_service.refresh_flow_in_cache( + db_flow, extra_keys=[previous_endpoint] + ) ... - await flow_cache_service.remove_flow_from_cache(db_flow) + await flow_cache_service.remove_flow_from_cache( + db_flow, extra_keys=[previous_endpoint] + )Coordinate with the updated cache service to accept the
extra_keys.Likely an incorrect or invalid review comment.

Restore orphaned-flow handling for flows without folders
Switching to an inner join on models.Folder means any orphaned flow whose folder_id is NULL is now filtered out, so we never reassign it to the superuser. That regresses the original behavior (these flows remain orphaned). Update the query to keep folder-less flows—use an outer join and guard the starter-folder check accordingly.

Endpoint aliases linger in cache after undeploy/rename
We cache flows under both UUID and endpoint_name, but remove_flow_from_cache only deletes the UUID. When a flow is undeployed or its endpoint is changed, the stale endpoint key keeps serving the old graph, so GET /run/{endpoint} still executes a supposedly DRAFT flow. Please delete every alias (current endpoint plus any extra keys you pass in) when evicting.
One way to address it:
- async def remove_flow_from_cache(self, flow: Flow, *, silent: bool = False) -> None:
+ async def remove_flow_from_cache(

Cache miss check misclassifies valid graphs
if not cached treats any falsy Graph instance as a miss. Graphs with no vertices (e.g., an empty {"nodes": [], "edges": []}) evaluate to False, so cached deployments of empty flows are dropped and the caller gets None. Explicitly compare against the cache miss sentinel instead of relying on truthiness.
Apply this diff:
- if not cached:
+ if cached is None or cached is CACHE_MISS:
return None(Import CACHE_MISS from langflow.services.cache.utils at the top if it’s not already available.)

Fix deploy/publish toggles to use the next checked state
Both switches derive the next status from isPublished/isDeployed captured at render time. If the user clicks twice before the store re-renders (e.g., disable and immediately re-enable), we keep sending the old value and leave the flow in the wrong state (confirmed when starting in DEPLOYED, clicking to draft, then immediately clicking again — we ship DEPLOYED → DRAFT twice and the flow stays drafted). Read the final checked value from the switch instead of recomputing from stale props.

🛠️ Refactor suggestion | 🟠 Major
Tests lack behavioral verification.
The current tests are smoke tests that only verify the component renders without crashing. They don't validate the actual deployment toggle behavior, UI state changes, or error handling.
Suggested additions:
- Test that clicking the deploy toggle calls
mutateAsyncwith correct parameters - Verify UI updates after successful deployment status change
- Test error handling when deployment toggle fails
- Verify the deployment status indicator displays correctly
Example test structure:
it("calls mutateAsync when deploy toggle is clicked", async () => {
const user = userEvent.setup();
render(<ToolsTable {...mockProps} />);
const deployToggle = screen.getByRole("switch");
await user.click(deployToggle);
expect(mockMutateAsync).toHaveBeenCalledWith({
id: "test-flow-id",
status: "DEPLOYED"
});
});As per coding guidelines: Tests must validate behavior and cover error conditions, not just render without crashing.

Critical: status collision (boolean selection vs deployment state) + stale setData + error handling
status is already used elsewhere here as a boolean (selection). This new usage sets it to a string (DRAFT/DEPLOYED), causing logic breakage (e.g., Line 94 and 101 filters, Lines 154–170 mapping). Store deployment state under a separate key (e.g., deploymentStatus) and use functional setState. Also extract error messages robustly.
Apply within this block:
- const handleDeployToggle = async (flowId: string, currentStatus: string) => {
+ const handleDeployToggle = async (flowId: string, currentStatus: string) => {
const newStatus =
currentStatus === DEPLOYMENT_STATUS.DEPLOYED

try {
await mutateAsync({

status: newStatus,
});
// Update the focused row to reflect the change

};Also update other usages in this component to use deploymentStatus for deployment state and a separate selected boolean for selection (see snippet in another comment).

Use deploymentStatus and onCheckedChange for Switch
Prevent collision with selection status and use the checked boolean directly from the Switch handler.

)}Outside these ranges, update selection logic to use a separate selected boolean to avoid clobbering the deployment status:
// On mount
const initialData = cloneDeep(rows).map((r) => ({
...r,
deploymentStatus:
typeof r.status === "string"
? r.status
: r.deploymentStatus ?? DEPLOYMENT_STATUS.DRAFT,
selected:
typeof r.status === "boolean" ? r.status : r.selected ?? false,
}));
setData(initialData);
// Filters
const filter = initialData.filter((row) => row.selected === true);
// In applyInitialSelection
const filter = cloneDeep(rows).filter((row) => row.selected === true);
// When emitting value on close, keep original contract (status as selection boolean)
// but avoid mutating internal deploymentStatus in data state.
status: selectedRows?.some(...) ? true : false🤖 Prompt for AI Agents
In src/frontend/src/modals/toolsModal/components/toolsTable/index.tsx around
lines 397-435, the Switch is currently using the row's status field and onClick
which collides with selection semantics; change the component and state usage to
use a separate deploymentStatus field for deployment state and a selected
boolean for selection, use the Switch's onCheckedChange (or onChange boolean
handler) instead of onClick, bind checked to row.deploymentStatus ===
DEPLOYMENT_STATUS.DEPLOYED, update the handler to accept the boolean checked and
set deploymentStatus accordingly (without mutating the original
status/selection), and update initialization, filters, applyInitialSelection and
the final emitted payload so internal data uses deploymentStatus/selected while
keeping the external contract that status is a selection boolean when emitting
on close.

🧩 Analysis chain
Verify placement of component reset in execution flow.
The _reset_components_in_vertices() call is positioned after collecting outputs but before returning. This looks correct for cleanup purposes, but verify that:
- The reset doesn't affect the collected
vertex_outputs(likely fine since outputs are collected first) - This is the right lifecycle point for all execution paths (normal completion, errors, etc.)
🏁 Script executed:
#!/bin/bash
# Check if there are other return paths or error handlers that should also call reset
rg -n -C5 'return vertex_outputs' --type=pyLength of output: 1752
Add missing component reset to arun return path
- Insert
self._reset_components_in_vertices()before thereturn vertex_outputsat line 877 inasync def arunto ensure cleanup runs on all execution paths. - Consider wrapping the method body in a
try/finallyso reset occurs even on errors.
🤖 Prompt for AI Agents
In src/lfx/src/lfx/graph/graph/base.py at lines 812-877, the async def arun path
is missing a call to self._reset_components_in_vertices() on the normal return
path and should ensure cleanup on exceptions; add
self._reset_components_in_vertices() immediately before the return
vertex_outputs at line ~877 and refactor the method body to use a try/finally
where the finally block calls self._reset_components_in_vertices() so the reset
runs on both successful returns and on errors.

146-177: Fix cachedGraphhandling insimple_run_flow.
simplified_run_flownow injects a cachedGraph(fromget_flow_by_id_or_endpoint_name_from_cache), butsimple_run_flowstill assumes a Flow/FlowRead object and accessesflow.id,flow.name, andflow.data. For cached requests this explodes withAttributeErrorbefore execution, breaking the new cache path entirely. Please branch onisinstance(flow, Graph)(or adjust the dependency to always supply a Flow-like object) so the cached Graph can run without touching Flow-only attributes. Until this is fixed, every cache hit will 500.

src/frontend/src/controllers/API/queries/flows/use-patch-update-flow.ts (1)
17-17: Consider extracting the status type to a shared constant.The
"DRAFT" | "DEPLOYED"type is duplicated across multiple files (this file,src/frontend/src/types/mcp/index.ts, andsrc/frontend/src/types/flow/index.ts). Extract it to a shared constant to improve maintainability and ensure consistency.For example, create a constant in a shared types file:
// src/frontend/src/constants/flows.ts or types file export const DEPLOYMENT_STATUS = { DRAFT: "DRAFT", DEPLOYED: "DEPLOYED", } as const; export type DeploymentStatus = typeof DEPLOYMENT_STATUS[keyof typeof DEPLOYMENT_STATUS];Then use it as:
interface IPatchUpdateFlow { id: string; name?: string; data?: ReactFlowJsonObject; description?: string; folder_id?: string | null | undefined; endpoint_name?: string | null | undefined; locked?: boolean | null | undefined; access_type?: "PUBLIC" | "PRIVATE" | "PROTECTED"; - status?: "DRAFT" | "DEPLOYED"; + status?: DeploymentStatus; }src/backend/base/langflow/services/flow_cache/service.py (1)
123-178: Memory calculation is approximate.The
get_cache_statsmethod usessys.getsizeofwhich provides only shallow size estimates, not deep object sizes. This is acknowledged in the comments (lines 139-141), but consider whether this approximation is sufficient for production monitoring. If precise memory tracking is needed, consider using libraries likepympleror implementing recursive size calculation.src/backend/tests/unit/api/v1/test_mcp_projects.py (1)
685-835: Add teardown for created users/projects/flows; prefer enum over magic strings
- These tests create DB rows without cleanup. Add teardown (or use fixtures with finalizers) to avoid cross-test interference.
- If a backend enum for deployment status exists, use it instead of literal "DRAFT"/"DEPLOYED" to reduce brittleness. Otherwise, keep as-is.

88-99: Use onCheckedChange and pass next state; fix inverted publish logicCurrent toggles work but are inconsistent (publish uses current state, deploy uses next) and rely on onClick. Prefer onCheckedChange with next-state semantics for correctness and accessibility.

237-246: Unique endpoint_name constraint may still violate on commitConstraint UniqueConstraint("user_id", "endpoint_name") can still conflict when reassigning. Consider normalizing conflicting endpoint_name (e.g., set to None or generate a unique suffix) similarly to names to avoid IntegrityError.

367-384: The tooltip test doesn’t assert tooltip contentComment says it should show specific text, but the test only checks item presence. Add a hover and assert the tooltip text.
Example:
- // The tooltip should show "Deploy this flow to make it available" for DRAFT status - await waitFor(() => { - const deployedStatus = screen.getByTestId("deployed-status"); - expect(deployedStatus).toBeInTheDocument(); - }); + const item = await screen.findByTestId("deployed-status"); + await userEvent.hover(item); + expect(await screen.findByText(/Deploy to make this flow available via API/i)).toBeInTheDocument();

44-62: Replace arbitrary timeouts with condition-based waits to reduce flakinessMultiple waitForTimeout calls can cause flakes. Prefer waiting on locators or state.
Examples:
- After opening dropdown:
- await page.waitForTimeout(3000); - await page.waitForSelector('[data-testid="deployed-status"]', { timeout: 10000 }); + await page.getByTestId("deployed-status").waitFor({ state: "visible", timeout: 10000 });
- After toggling:
- await page.waitForTimeout(2000); - await expect(page.getByTestId("deploy-switch")).toBeChecked({ checked: true }); + await expect(page.getByTestId("deploy-switch")).toBeChecked({ checked: true });
- Use expect visibility/checked assertions directly; they inherently wait.
Also applies to: 62-76, 86-94
145-165: Lock behavior not assertedThe test doesn’t verify that nodes can’t be moved/edited when deployed. Add a concrete assertion (e.g., drag attempt has no effect or lock icon appears).
Example:
const node = page.locator('[data-testid*="title-Chat Input"]'); const boxBefore = await node.boundingBox(); await node.dragTo(page.getByTestId("rf__wrapper")); // or simulate drag by mouse const boxAfter = await node.boundingBox(); expect(boxAfter).toEqual(boxBefore); // unchanged if locked

Line 41 uses a shallow copy (

However, sinceGraph.from_payloadlikely doesn't mutate the input, this should be safe.Lines 46-49 catch broad exception types. While this is acceptable for graceful degradation, consider whether more specific exception types could improve diagnostics.

Outer-join and proper NULL comparisons to include folderless flows
Current inner join excludes orphaned flows without a folder. Also uses == None and an implicit join target. Use an outer join on Flow.folder and is_(None) plus an OR to include NULL folders.

- select(models.Flow)
- .join(models.Folder)

217, the current inner join and `== None` check exclude flows that have no
folder; change to use an outer (left) join against the Flow.folder relationship
and replace `== None` with SQLAlchemy's `is_(None)`; then adjust the WHERE so
flows with user_id is_(None) AND (Folder.name != STARTER_FOLDER_NAME OR
Folder.id is_(None)) so folderless flows are included. Ensure you use an
explicit outerjoin on the relationship (e.g. outerjoin(models.Flow.folder)) and
import and use sqlalchemy.or_ or the `|` operator for the OR condition.

Critical: log_vertex_build signature mismatch — missing DB session and schema
The imported crud.log_vertex_build expects (db: AsyncSession, vertex_build: VertexBuildBase, ...). Current call passes flow_id/vertex_id/etc. without a DB session, causing a TypeError at runtime. Fix by creating a session and passing a VertexBuildBase payload.

🤖 Prompt for AI Agents
In src/backend/base/langflow/services/socket/utils.py around lines 5-15 (and
also apply same fix to lines 90-97), the call to log_vertex_build is using the
wrong signature: the CRUD expects an Async DB session and a VertexBuildBase
schema instance but the current code passes primitive values (flow_id,
vertex_id, etc.) without a session. Fix by acquiring an async DB session via
get_session(), construct the proper VertexBuildBase (or the expected
vertex_build schema) with the flow/vertex/status/message/timings data, and call
await log_vertex_build(db_session, vertex_build_payload, ...) instead of the
current argument list; ensure the session is closed/used as an async context
manager if required.

🛠️ Refactor suggestion | 🟠 Major
Enhance tests to validate actual deployment status behavior.
These tests only verify that the component renders without crashing but don't validate the deployment status functionality. They should test:
- That deployment status badges/indicators are actually visible in the UI
- That the deploy toggle switch works correctly
- That toggling deployment status calls the mock API (
mockMutateAsync) - That status changes update the UI state appropriately
Consider enhancing the tests like this:
it("displays deployment status for deployed flow", () => {
const { container } = render(
<ToolsTable
rows={[mockDeployedFlow]}
data={[mockDeployedFlow]}
setData={jest.fn()}
isAction={true}
placeholder="Search"
open={true}
handleOnNewValue={jest.fn()}
/>,
);
- // The component uses ag-grid which needs special handling
- // Just verify it renders without crashing
- expect(container).toBeInTheDocument();
+ // Verify deployment status is visible
+ // This will depend on how the component displays status - add appropriate assertions
+ expect(container).toBeInTheDocument();
+
+ // Example: Verify deployment badge/indicator exists
+ // expect(screen.getByText(/deployed/i)).toBeInTheDocument();
+ // or expect(screen.getByTestId("deployment-badge")).toHaveTextContent("DEPLOYED");
});Based on coding guidelines.

Test validates mock data structure instead of component behavior.
This test only verifies properties on the mock objects rather than testing how the component handles and displays the status field. It should verify that:
- The component correctly reads the
statusfield from flow data - The UI reflects different status values (DEPLOYED vs DRAFT) appropriately
- User interactions with status-related controls work as expected
Consider testing actual component behavior:
it("includes status field in flow data", () => {
const mockSetData = jest.fn();
render(
<ToolsTable
rows={[mockDeployedFlow, mockDraftFlow]}
data={[mockDeployedFlow, mockDraftFlow]}
setData={mockSetData}
isAction={true}
placeholder="Search"
open={true}
handleOnNewValue={jest.fn()}
/>,
);
- // Verify the component can handle flows with status field
- expect(mockDeployedFlow.status).toBe("DEPLOYED");
- expect(mockDraftFlow.status).toBe("DRAFT");
+ // Verify the component displays different status values correctly
+ // Add assertions that check how the UI reflects deployed vs draft status
+ // For example:
+ // const deployedBadges = screen.getAllByText(/deployed/i);
+ // expect(deployedBadges).toHaveLength(1);
+ // const draftBadges = screen.getAllByText(/draft/i);
+ // expect(draftBadges).toHaveLength(1);

Prevent stale state when toggling deployment
handleDeployToggle relies on the captured focusedRow/data values from the render that kicked off the mutation. If anything else updates those states before the patch resolves (e.g., another toggle or external list refresh), the subsequent setFocusedRow/setData(data.map(...)) call will overwrite newer changes with stale copies. Use the functional form of the setters so the update is applied to the latest state instead of the closed-over snapshot.

Test doesn't validate deployment toggle behavior.
This test is overly defensive and doesn't actually verify that deployment status can be toggled. Key issues:
- Lines 70-71:
expect(true).toBe(true)is a placeholder assertion that always passes - The extensive try/catch with
test.skip()means the test passes even if it encounters any error - No verification that clicking the toggle actually calls the API or updates the status
This violates the coding guideline: "Tests should not be mere smoke tests; they must validate behavior"
Either enhance the test to validate actual toggle behavior or rename it to reflect that it only checks element visibility:
- test(
- "MCP modal allows toggling deployment status",
+ test(
+ "MCP modal and tools button are accessible",
{ tag: ["@release", "@workspace", "@api"] },
async ({ page }) => {
test.setTimeout(60000);
try {
await awaitBootstrapTest(page);
// ... existing code ...
- // Test passes if we got this far
- expect(true).toBe(true);
+ // Verify the modal opened successfully
+ await expect(
+ page.getByRole("heading", { name: "MCP Server Tools" })
+ ).toBeVisible({ timeout: 5000 });
} catch (error) {
console.log("Test skipped:", error);
test.skip();
}
},
);Or implement actual toggle testing if elements are reliably present.

In src/frontend/tests/core/features/mcp-deployment.spec.ts around lines 34-77,
the test currently contains placeholder assertions and broad try/catch that
cause it to always pass or be skipped; replace the placeholder with real
validation: remove the outer catch that swallows errors, only use conditional
test.skip() before any interactions if prerequisites aren't present, then locate
the deployment toggle element, assert its initial state, click it, and assert
the state changed in the UI; also spy or wait for the relevant network/API
request and assert it was called with expected payload (or mock the response) to
confirm backend interaction; ensure failures throw so the test fails when
behavior is incorrect and keep timeouts minimal and explicit.

Added docstrings to the FlowCacheServiceFactory class and its methods to improve code clarity and maintainability. The new documentation includes descriptions of the class purpose, initialization, and the singleton creation logic for FlowCacheService instances, ensuring better understanding for future developers.
Deleted the unused `/cache` endpoint from the API, streamlining the codebase and improving maintainability. Additionally, removed unnecessary imports related to the flow cache service, enhancing code clarity.
Refactored existing tests in the ToolsTable component to improve clarity and accuracy. Renamed test cases to better reflect their purpose, ensuring they check for proper rendering and handling of deployment statuses. Added new tests to verify the component's response to status updates and the invocation of the mutateAsync function during deployment toggles, enhancing the robustness of the test suite.
Enhanced the flow creation process by locking flows with a DEPLOYED status prior to committing to the database. Updated comments to clarify the caching behavior for deployed flows, ensuring better understanding and maintainability of the flow management logic.
Introduced a new test to verify that flows created with a DEPLOYED status are automatically locked upon creation. This enhances the test suite by ensuring the correct behavior of flow management during the creation process, contributing to the overall robustness of the application.
Changed the status field in the MCPSettings model to use a Literal type for "DRAFT" and "DEPLOYED" values. This improves type safety and clarity in the model definition, ensuring that only valid status values are used throughout the application.
Refactored the get_components_versions function to streamline the process of retrieving graph_data or data from the flow object. The new implementation uses getattr for safer access and includes checks to ensure the retrieved data is a dictionary, improving code clarity and robustness.
Updated the flow cache service to support removal of stale cache entries when a flow's endpoint name changes. The `remove_flow_from_cache` and `refresh_flow_in_cache` methods now accept an optional `old_endpoint_name` parameter, allowing for more robust cache management during flow updates. This change improves the handling of renamed flows and ensures that all associated cache keys are properly cleaned up.

🚀 New features to boost your workflow:

The goal here is two fold: allow users to promote flows into something akin to staging/production status, cache flows in-memory to avoid db queries when running the flow.
To achieve the first one, Flows now have a
statuscolumn that can be set toDRAFTorDEPLOYEDwhich puts or removes flows from theFlow Cache. The key thing here is that what we want is for flows to be inacessible through the API if not deployed which is a breaking change, so, for now, "DRAFT" status means <1.7.0 behavior (not cached), "DEPLOYED" status means cached.To achieve the second one a "FlowCacheService" was created and endpoints updated, including mcp endpoints.
