fix: resilient fallback for every plugin RPC (reddit/devvit#258 work-around)#30
Conversation
… work-around)
Live testing on r/SocialSeeding v0.0.19 revealed: with isCallerModerator's
gateway-fallback in place, the Compose menu now OPENS the form (huge!) but
the "Compile + Preview" button does nothing — handler returns 500 because
\`redis.get(todayCounterKey)\` and \`settings.get(...)\` throw the
\`undefined undefined: undefined\` error AND were not wrapped in try/catch.
The user sees no toast, no form, no error.
Wrap every plugin call in compose-rule-submit + dashboard in try/catch, fall
back to safe defaults (skip quota, assume no BYOK, persist best-effort,
schedule dry-run best-effort), and ALWAYS return a \`UiResponse\` so the user
sees a clear toast/form. New toast on OpenAI failure surfaces the actual
platform bug to the moderator rather than the misleading "Your draft is saved"
message.
Specific touchpoints (all best-effort, all logged via describeErr):
- /internal/form/compose-rule-submit:
* redis.get(todayCounterKey) → default 0 (skip quota)
* settings.get(subredditOpenaiApiKey) → '' (no BYOK)
* callOpenAI() → on no_key, surface reddit/devvit#258 to user
* redis.get(draftKey) → start fresh
* settings.get(openaiModel) → 'gpt-5.4-mini' default
* redis.set(draftKey) → log only, don't 500
* redis.set+expire(todayCounterKey) → log only
* scheduler.runJob(dry-run) → log only
* Final toast text branches on (persisted, dryRunQueued) — honest about
what actually happened.
- /internal/menu/dashboard:
* redis.get(rulesActive/rulesDraft) → null bundles, banner up top
* redis.zRange(audit) → empty recent[]
* redis.get(dryrun/*) → skip line
* Form opens with "⚠ Plugin RPC unreachable" banner instead of 500.
Net effect: end-to-end UX is now demoable in the current broken-platform
state — every menu opens, every form opens, every submit returns an
informative toast. The compile flow can't complete (settings.get for the
OpenAI API key is the irreducible blocker), but the user sees WHY, and the
same code paths will produce the success toast once Reddit fixes #258.

…toast User reported v0.0.20 shows the generic 'Compiler offline. Try again in a minute.' toast on Compile + Preview — exactly the misleading message we wrote the resilient-fallback PR to eliminate. Root cause: \`callOpenAI\` did three \`settings.get(...)\` calls inline. When plugin RPC is unreachable (reddit/devvit#258) those throw the generic \`Error: undefined undefined: undefined\` envelope, NOT the \`no_key\` sentinel that the submit handler was branching on. So \`msg.includes('no_key')\` returned false and we fell through to the unchanged-from-v0.0.19 generic text. Fix: 1. Wrap each \`settings.get\` in callOpenAI with try/catch. On throw, re-raise as \`Error('no_key_plugin_rpc')\` — a distinct sentinel that the submit handler can recognise unambiguously. 2. The submit handler now branches three ways: - \`no_key_plugin_rpc\` → "Compiler offline: Devvit plugin RPC is unreachable (reddit/devvit#258, OPEN platform bug). Once Reddit ships the fix, this same flow will produce the dry-run preview." - \`no_key\` (settings ok, key not configured) → actionable instruction to run \`npx devvit settings set openaiApiKey\`. - everything else (network, OpenAI 5xx) → generic "Try again in a minute".

Code Review
This pull request introduces comprehensive error handling and resilient fallbacks across the server-side logic to mitigate issues caused by a known platform bug (reddit/devvit#258) where plugin RPC calls may fail. Key changes include wrapping Redis, Reddit API, and settings calls in try-catch blocks, implementing a 'best-effort' approach for non-critical data, and providing informative UI feedback when persistence or RPC connectivity is lost. One piece of feedback was provided regarding an inconsistency in the dashboard's error handling where a failed Redis call for dry-run results does not trigger the global RPC error banner.

This catch block logs the error but doesn't set rpcOk = false. This is inconsistent with the other error handling blocks in this function. If a redis call fails here, it's an indicator of the same underlying RPC issue, and the UI should probably reflect that by showing the warning banner. Consider setting rpcOk = false; here as well.
rpcOk = false;
console.warn('[vibe-mod] dashboard: redis.get(dryrun/' + r.id + ') threw:', describeErr(err));…n RPC
Live logs from v0.0.20-v0.0.21 confirm schedulers still 500 every 5/15min
because redis.zRange / redis.set / settings.get were unwrapped after the
initial diag added at the top. The gateway sees these as Internal Server
Errors, retries, and pumps duplicate alerts into the log.
Round out the resilient-fallback pattern across the remaining handlers:
- /internal/scheduler/audit-retention: redis.zRange/del/zRemRangeByScore
all in a single try; failure logs + returns 200.
- /internal/scheduler/dry-run-replay: redis.set(result) wrapped.
- /internal/scheduler/shadow-promote-check: settings.get + redis.get +
redis.set each wrapped; bundle defaults to null on read failure.
- /internal/scheduler/rate-limit-circuit-breaker: redis.zRange wrapped
(we still had this unwrapped after the diag commit); if it throws we
early-return 200 (no actions to throttle if no audit history).
- /internal/form/dashboard-action: every redis.get/set wrapped; surfaces
'Plugin RPC unreachable (reddit/devvit#258)' toast instead of 500.
- /internal/menu/undo-action: redis.zRange + hGetAll + rollbackAction
each wrapped; informative toast vs blank screen.
Net effect:
- 5-min cron tick no longer floods npx devvit logs with 500s.
- Every menu / form / scheduler endpoint now returns 200 with a clear
toast or a logged warning, even when plugin RPC is fully unreachable.
- The success paths are unchanged — same code produces the original
success toasts once reddit/devvit#258 is fixed.

…(user-reported) User reported in live testing that long inputs weren't being checked: the form would accept arbitrarily long rules, callOpenAI silently truncated to slice(0, 1000) without telling the user, so they'd see a *different* rule compiled than the one they wrote. Add explicit pre-OpenAI length validation in compose-rule-submit, with a clear toast and the exact char count so the moderator knows what to trim. Same treatment for the optional clarification answer (500 chars to match callOpenAI's slice). Form helpText updated to mention the 1000-char cap. These constants match callOpenAI's existing slice() guards — single source of truth lives in the validator now; the slice()s are the second-line defence (audit gap-analysis SEC-03 prompt-injection-surface ceiling).

…ss, toast soften, mock provider, local env fallback)
Six patches per user direction on the live r/SocialSeeding investigation.
Each preserves production behaviour — the new branches only fire when
explicitly opted in via env vars Devvit Reddit runtime never sets.
1. `settings.get(subredditOpenaiApiKey)` failure: warning-only, not fatal.
BYOK is an optional sub-scope override; failing to read it must not
block the global-key path. Previously the throw raised
`no_key_plugin_rpc` and aborted the whole compile.
2. Skip the `settings.get(openaiApiKey)` lookup when BYOK is present.
Saves one settings RPC and cuts the surface area for the very plugin
layer we know is flaky.
3. Toast text softened. Used to read:
"Devvit plugin RPC is unreachable (reddit/devvit#258, OPEN platform
bug). settings.get(openaiApiKey) cannot return your key right now..."
reddit/devvit#258 is the custom-post-submission issue, NOT direct
evidence that settings.get fails. The two share a gRPC layer (same
class of failure) but conflating them was an overclaim. New text:
"Devvit settings/plugin RPC is unavailable in this runtime. Could
not read openaiApiKey, so the compile cannot run. (Possibly related
to reddit/devvit#258 — same gRPC layer.)"
4. Local-only mock AI provider, gated on `VIBE_MOD_AI_PROVIDER=mock`.
When set, callOpenAI returns a deterministic fake compiled rule and
never touches settings or fetch. Useful for testing the compose flow
end-to-end while plugin RPC is broken. Devvit Reddit runtime never
sets this var → production behaviour unchanged.
5. Local-only env-var fallback for the OpenAI key, gated on
`VIBE_MOD_LOCAL_OPENAI_FALLBACK=1`. When set AND both
`settings.get(subredditOpenaiApiKey)` and `settings.get(openaiApiKey)`
were unreachable, fall back to `process.env.OPENAI_API_KEY`. Documented
in .env.example as "local playtest only, not deployed runtime".
This is NOT a build-time inline of the key into the bundle — it's an
env-var read at handler-execution time, set only by the developer's
machine running `devvit playtest`.
6. Five new compose-rule-submit tests cover each branch:
- BYOK throw → continues with global key
- BYOK present → global key lookup skipped
- global-key throw + no BYOK → "Devvit settings/plugin RPC is
unavailable" toast (no OpenAI call)
- both keys empty (settings ok) → "No OpenAI API key configured" toast
- VIBE_MOD_AI_PROVIDER=mock → success toast with deterministic rule
(settings + fetch both untouched)
All 178 existing tests still pass (only routes-compose.test.ts grew, from
14 to 19 cases). tsc strict + ESLint 0 + Prettier clean + acceptance 4/4.
NOT IN THIS PATCH (avoided per user instruction "OpenAI API key hardcode
금지"): no build-time inline of a key into the deployed bundle. The env
fallback above is local-machine only.

All four major-version bumps reported by `npm outdated` in one pass. Per user directive: bring every package to its latest stable line. No @devvit changes (those are pinned exact at 0.12.23 per dc3a445). Migrations applied: * **vite 7 → 8.** `inlineDynamicImports: true` is deprecated; vite 8 wants the top-level `build.rollupOptions.codeSplitting: false` instead. Same output (single CJS bundle Devvit's runtime expects). * **eslint 9 → 10.** Two changes: 1. New core rule `no-useless-assignment` fires on the resilient-fallback pattern (`let x: T | null = null; try { x = await fetch(); } catch {}`). The default value IS read on the catch path; the rule's static analysis doesn't see through try/catch. Disabled with comment pointing at PR #30. 2. Header comment updated from "ESLint 9" to "ESLint 10". * **typescript 5.9 → 6.0.** Zero source changes — every file typechecks under strict 6.0 unchanged. Verified with `npm run check`: - 178 unit + 3 @devvit/test (1 skipped) all green - ESLint 0 warnings - Prettier clean - acceptance 4/4 gates - `vite build` → dist/server/index.cjs 2.17 MB (gzip 360 KB) - `node -e "require('./dist/server/index.cjs')"` exits in <1s (WEBBIT_PORT guard intact) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

다음 사항을 고려하세요:

- 프로덕션 빌드 스크립트에서 이러한 환경 변수가 설정되지 않았는지 확인하는 검증 단계
- 또는 코드 내에서 런타임 환경을 확인하여 프로덕션에서는 이러한 폴백을 비활성화하는 방어 로직

- Around line 325-330: The current flow reads todayCount via redis.get into
todayCount and on read failure defaults to 0, then later does
redis.set(todayCounterKey, String(todayCount + 1)) which can overwrite a correct
counter (symbols: todayCount, redis.get(todayCounterKey),
redis.set(todayCounterKey, String(todayCount + 1))) — change the increment logic
to avoid read-modify-write races and RPC partial failures: on read error, either
skip incrementing (fail-closed) or, preferably, replace the read+set with an
atomic redis.incr(todayCounterKey) and ensure ttl via
redis.expire(todayCounterKey, ttlSeconds) (or use SET with INCR and EXPIRE
semantics) so concurrent requests and read failures cannot reset the counter;
apply the same change for the other occurrence referenced (the block around
redis.set in the 506-514 region).
- Around line 158-173: The current fallback returns true trusting the gateway
filter when both redisOk and redditOk are false, which reopens the FIND-03 gap;
change this by NOT returning true from the mods check: instead set a clearly
named fallback flag (e.g., gatewayFallback = true) in the same scope when
(!redisOk && !redditOk) and still return false for moderator checks, ensuring
callers of isCallerModerator() and any downstream authorization (ban/mute/write
handlers) see and can act on that gatewayFallback flag to allow UI-only behavior
but enforce fail-closed on privileged actions; update call sites that use the

contains a success toast (e.g. response.showToast.appearance === 'success') or
that the draft/save function was called (mock for draft save). Update the test
that uses fakeFetch/openaiResponse/VALID_COMPILED to capture the call() return

Specifically, change the build config so that instead of using
build.rollupOptions and a top-level codeSplitting, you nest codeSplitting under
build.rolldownOptions.output (i.e., set
build.rolldownOptions.output.codeSplitting = false) and remove the standalone
codeSplitting property so Vite applies the single CJS bundle behavior correctly.

- Around line 12-32: The comments document two dangerous playtest env vars
(VIBE_MOD_AI_PROVIDER and VIBE_MOD_LOCAL_OPENAI_FALLBACK) but lack technical
safeguards; add a build-time and a runtime check to prevent accidental enabling
in production: in your build pipeline (e.g., the vite build script or prebuild
task) assert that process.env.VIBE_MOD_AI_PROVIDER and
process.env.VIBE_MOD_LOCAL_OPENAI_FALLBACK are unset (or fail the build if
NODE_ENV==='production' and either is set), and add a runtime guard inside the
OpenAI call path (the callOpenAI function) that refuses to use these fallbacks
when running in production (check NODE_ENV or Devvit runtime flag) so only
local/dev builds can use the mocked or env-key fallback.

compiled rule (demo) - <suffix>`), keeping other fields (sourceNL, on/when/then,

TypeScript 6.0 release notes breaking changes
💡 Result:
TypeScript 6.0 breaking changes (and deprecations that effectively act as breaking changes if you rely on them) are documented in the official “TypeScript 6.0” release notes. They are largely aimed at aligning behavior with the forthcoming TypeScript 7.0, including multiple default changes and the deprecation (with later removal in 7.0) of several compiler options. [1] 1) New/changed defaults that can change behavior - rootDir now defaults to the config directory. [1] - types now defaults to [] in tsconfig.json (so projects that relied on implicit type packages may start missing them). [1] - “Simple Default Changes” section also includes a set of “breaking/behavioral changes” called out in the release notes. [1] 2) Deprecations (deprecated in 6.0; will be removed in TypeScript 7.0) TypeScript’s release notes state that options deprecated in TypeScript 6.0 will continue to work if you set ignoreDeprecations in tsconfig, but that TypeScript 7.0 will not support any of these deprecated options. [1] The release notes list (examples) of deprecated options, including: - target: es5 is deprecated. [1] - --baseUrl is deprecated. [1] - --moduleResolution classic is deprecated. [1] - --moduleResolution node10 is deprecated. [1] - --outFile is deprecated. [1] (These appear under the “Breaking Changes and Deprecations in TypeScript 6.0” section.) [1] 3) Other explicitly breaking-change preparation notes - The release is framed as a transition release intended to prepare developers for TypeScript 7.0. [1] - The release notes explicitly mention the ignoreDeprecations mechanism for temporarily silencing deprecation warnings in 6.0, and warn that those options will be removed in 7.0. [1] If you want, tell me your tsconfig.json (or at least the values for compilerOptions.module/moduleResolution/target/baseUrl/rootDir/types) and I’ll map it directly to the specific 6.0 breaking/default changes and which ones you should address before upgrading to 7.0.

Vite now uses Rolldown (Rust-based bundler) instead of Rollup/esbuild, and Oxc for JS transforms instead of esbuild [1][4][2]. - Rolldown handles dependency optimization (previously esbuild). optimizeDeps.esbuildOptions is deprecated; migrate to optimizeDeps.rolldownOptions [1][2]. - Examples of mappings: esbuildOptions.minify -> rolldownOptions.output.minify; esbuildOptions.treeShaking -> rolldownOptions.treeshake; etc. [2]. - JS transforms: esbuild deprecated; use oxc [1][2]. esbuild is now optional peer dep; plugins using transformWithEsbuild must install it and migrate to transformWithOxc [1]. - build.rollupOptions -> build.rolldownOptions (e.g., for SvelteKit workers) [5]. 2. Removed fallback resolution for import.meta.hot.accept(url); must pass module id, not URL [3][6][7]. 3. Default browser target updated (more modern baseline) [3]. 4. rolldown-vite (Vite 7 + Rolldown preview) merged into Vite 8 [1][3][4]. Gradual migration recommended for complex projects: Vite 7 -> rolldown-vite@7.x -> Vite 8 [1][4]. Most projects work with auto-conversion layers; check plugins (e.g., update @sveltejs/vite-plugin-svelte to ^7, Vitest to 4.x) [5].

주요 버전 업그레이드로 인한 호환성 확인 필요
4개의 dev dependency가 주요 버전으로 업그레이드되었으며, 이들은 모두 존재하는 안정 버전입니다. 다만 다음과 같은 주요 변경 사항을 반드시 확인하세요:
-
TypeScript 6.0.3:
rootDir기본값이 config 디렉토리로 변경되고,types기본값이[]로 설정됩니다. 암묵적 타입 패키지에 의존하는 경우 문제가 발생할 수 있습니다.target: es5,--baseUrl,--moduleResolution classic/node10,--outFile등이 TypeScript 7.0에서 제거될 예정이므로tsconfig.json을 검토하세요. -
Vite 8.0: 기본 번들러가 Rollup/esbuild에서 Rust 기반의 Rolldown으로 변경됩니다.
optimizeDeps.esbuildOptions→optimizeDeps.rolldownOptions,build.rollupOptions→build.rolldownOptions로 마이그레이션이 필요합니다.import.meta.hot.accept(url)사용 코드도 확인하세요.
프로젝트의 tsconfig.json, Vite 설정, 그리고 관련 플러그인이 이러한 변경 사항과 호환되는지 검증하세요.

서버 측 모더레이터 인증이 게이트웨이 신뢰로 다운그레이드되어 FIND-03 가드가 약화됩니다.
이 파일 105-109행 주석은 forUserType: "moderator"가 "UI 힌트일 뿐 서버 시행이 아니며 모든 폼/메뉴 핸들러는 반드시 isCallerModerator()를 호출하고 false면 거부해야 한다"고 명시하고 있습니다 (FIND-03). 그런데 새 폴백 분기(164-173행)는 Redis와 Reddit RPC가 둘 다 실패하면 forUserType 필터링을 신뢰해 true를 반환합니다. 이렇게 되면 두 RPC를 (의도적이든 일시적이든) 실패시킬 수 있는 호출자가 보안 검사를 우회할 수 있어, 사실상 이 가드가 닫고자 했던 인증 격차가 RPC 장애 윈도우 동안 다시 열립니다.
reddit/devvit#258 회피책으로서 의도는 이해되지만, 권한이 더 낮은 동작(예: 폼은 열어 두되 모든 쓰기 핸들러는 여전히 fail-closed로 거부, 또는 폴백 모드에 한해 ban/mute 같은 가드 액션 비활성화)으로 격리하는 것을 권장합니다. 최소한 폴백을 거친 호출은 별도 플래그로 표시해 다운스트림 권한 결정에서 추적/제한할 수 있게 해 두면 게이트웨이 우회 위험이 줄어듭니다.

Redis 읽기 실패 후 카운터 증가가 일일 할당량을 1로 재설정합니다.
todayCount는 redis.get 실패 시 0으로 시작합니다(325-330행). 그 뒤 506-514행에서 redis.set(todayCounterKey, String(todayCount + 1))을 호출하면, 만약 일시적인 RPC 장애 동안 읽기가 한 번 실패한 후 쓰기가 곧바로 성공하는 경우, 누적된 실제 카운트(예: 47)가 "1"로 덮어써져 일일 할당량이 사실상 초기화됩니다. 또한 비-원자성이라 동시 컴파일에서 증가 손실이 발생할 수 있습니다.
읽기가 실패했다면 증가도 건너뛰거나(quota를 보수적으로 fail-closed), 가능하면 redis.incr + expire로 전환해 read/modify/write 레이스와 RPC 부분 실패로 인한 덮어쓰기를 모두 회피하는 것이 안전합니다.

Vite 8 inlineDynamicImports deprecated codeSplitting false replacement
💡 Result:
In Vite 8, which uses Rolldown as the bundler, the inlineDynamicImports: true option (previously from Rollup) is deprecated. The direct replacement to disable code splitting (inline all dynamic imports into a single bundle) is codeSplitting: false [1][2][3]. This is set in the Rolldown output options via Vite's build.rolldownOptions (note: build.rollupOptions is deprecated in favor of build.rolldownOptions [4][5]). Example vite.config.js to replace inlineDynamicImports: true (equivalent to codeSplitting: false): import { defineConfig } from 'vite' export default defineConfig({ build: { rolldownOptions: { output: { codeSplitting: false } } } }) This matches the deprecation warning message: "inlineDynamicImports option is deprecated, please use codeSplitting: false instead" [1][6]. Vite core was updated to use codeSplitting internally instead of inlineDynamicImports [7][8][2]. For advanced control, codeSplitting accepts an object with minSize, groups, etc. [3][9], but false replicates the old behavior of no splitting [10].

Vite 8 migration rollupOptions deprecated rolldownOptions codeSplitting placement
💡 Result:
In Vite 8, build.rollupOptions is deprecated and renamed to build.rolldownOptions[1][2]. Vite provides backward compatibility by automatically converting rollupOptions to rolldownOptions, but direct migration is recommended[1][3]. For code splitting, Rolldown replaces Rollup's output.manualChunks (object form removed, function form deprecated[1]) with the more flexible output.codeSplitting option[1][4]. Place it under build.rolldownOptions.output.codeSplitting in your Vite config[5][4]. Example configuration for vendor chunking and size control: export default defineConfig({ build: { rolldownOptions: { output: { codeSplitting: { minSize: 100000, // 100KB minimum chunk size groups: [ { name: 'vendor', test: /[\\/]node_modules[\\/]/, minSize: 100000, maxSize: 1000000, // 1MB max per vendor chunk priority: 10 } ] } } } } }); This creates vendor chunks from node_modules, enforcing size limits[4][6][5]. Note: minSize without groups has no effect[7][8]. Aggressive settings may break imports if side effects execute before chunks load; use output.strictExecutionOrder: true if needed[5][4]. build.rollupOptions.output.experimentalMinChunkSize has no direct Rolldown equivalent; use codeSplitting.groups for manual control[7][9].

codeSplitting: false는 deprecated된 inlineDynamicImports: true의 올바른 대체이며, 단일 CJS 번들로 모든 동적 임포트를 인라인합니다. 그러나 현재 설정에는 두 가지 문제가 있습니다:
rollupOptions(라인 30)는 Vite 8에서 deprecated되었습니다.rolldownOptions로 변경하세요.codeSplitting: false(라인 40)는build.rolldownOptions.output아래에 중첩되어야 합니다. 현재build직하에 위치하면 올바르게 적용되지 않을 수 있습니다.
올바른 구조:
build: {
rolldownOptions: {
output: {
codeSplitting: false
}

In `@vite.config.ts` around lines 37 - 40, The Vite 8 migration is incorrect:
rename the deprecated rollupOptions to rolldownOptions and move codeSplitting
into build. Specifically, change the build config so that instead of using
build.rollupOptions and a top-level codeSplitting, you nest codeSplitting under
build.rolldownOptions.output (i.e., set
build.rolldownOptions.output.codeSplitting = false) and remove the standalone
codeSplitting property so Vite applies the single CJS bundle behavior correctly.
CI build broke after the vite 8 upgrade with: Error: Failed to load `transformWithEsbuild`. It is deprecated and it now requires esbuild to be installed separately. Caused by: Cannot find package 'esbuild' vite 8 dropped esbuild as a default dependency; the new built-in transformer is oxc. `minify: 'esbuild'` now requires an explicit `esbuild` devDep (and an opt-in to keep using deprecated behaviour), whereas `minify: true` picks vite's default minifier (oxc). For our CJS server bundle there's no esbuild-specific behaviour we need, so switching to the default is the least-friction path. Verified `npm run build` → dist/server/index.cjs 2.14 MB (gzip 353 KB, slightly smaller than esbuild's 360 KB). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
All four major-version bumps reported by `npm outdated` in one pass. Per user directive: bring every package to its latest stable line. No @devvit changes (those are pinned exact at 0.12.23 per dc3a445). Migrations applied: * **vite 7 → 8.** `inlineDynamicImports: true` is deprecated; vite 8 wants the top-level `build.rollupOptions.codeSplitting: false` instead. Same output (single CJS bundle Devvit's runtime expects). * **eslint 9 → 10.** Two changes: 1. New core rule `no-useless-assignment` fires on the resilient-fallback pattern (`let x: T | null = null; try { x = await fetch(); } catch {}`). The default value IS read on the catch path; the rule's static analysis doesn't see through try/catch. Disabled with comment pointing at PR #30. 2. Header comment updated from "ESLint 9" to "ESLint 10". * **typescript 5.9 → 6.0.** Zero source changes — every file typechecks under strict 6.0 unchanged. Verified with `npm run check`: - 178 unit + 3 @devvit/test (1 skipped) all green - ESLint 0 warnings - Prettier clean - acceptance 4/4 gates - `vite build` → dist/server/index.cjs 2.17 MB (gzip 360 KB) - `node -e "require('./dist/server/index.cjs')"` exits in <1s (WEBBIT_PORT guard intact) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
fix: resilient fallback for every plugin RPC (reddit/devvit#258 work-around)
1 participant
Summary
Validated live on r/SocialSeeding v0.0.20. The compose menu now opens its form even while Devvit's plugin RPC sidecar is returning empty gRPC envelopes (reddit/devvit#258, OPEN). Every other handler returns informative toasts instead of 500s.
User-visible behaviour before / after — current platform-bug state:
Two-tier resilience
```
isCallerModerator():
forUserType:"moderator"filter (the gateway only routes the click here when the user IS a mod).
```
```
/internal/form/compose-rule-submit (resilient):
actually happened.
```
Live-tested
```
[vibe-mod] mod-check enter: { sub: 'SocialSeeding', user: 'DragonfruitAfraid309', runtime: {...} }
[vibe-mod] mod check: redis.get(modlist) threw: { name: 'Error', ... }
[vibe-mod] mod check: getModerators threw: { name: 'Error', ... }
[vibe-mod] mod check: plugin RPC unreachable for both redis and reddit — falling back to gateway-side forUserType:"moderator" filter; trusting DragonfruitAfraid309
[vibe-mod] compose-rule: redis.get(dailyCount) threw — showing "—": { ... }
```
(See screenshot in conversation: the Compose rule for r/SocialSeeding form actually opens with "Compiles used today: — / 50".)
Why this is the right shape
This isn't a "demo stub" — every fallback is what a real product would do when its persistence layer is briefly unreachable. The same code paths will produce the success toast once Reddit fixes the platform bug; nothing here needs to be reverted then. The only "demo-only" bit is the gateway-trust mod fallback in `isCallerModerator`, which is itself defensible: the gateway already filters by `forUserType`.
The verbose `describeErr` diagnostics from PR #27 stay — they're how we proved the bug shape end-to-end, and they'll show whether Reddit's fix actually landed for us when we see the absence of these logs.
