502 Bad Gateway when Replying to A365 Activities Using the Sample Project

[fanzeyi]

Hi, I am testing the Python sample project in https://github.com/microsoft/Agent365-Samples/tree/main/python/agent-framework/sample-agent with a testing Azure account with A365 enabled, but it runs into issues when trying to generate a reply.

Error Message:

Setup

I made some changes to the sample project attempting to get it working. Here are all the changes:

I can see in the logs that the agent was able to acquire all necessary scopes it needed but McpToolRegistrationService (I'm guessing we probably don't have access to that).

So I have this modification in agent.py

-            self.tool_service = McpToolRegistrationService()
+            self.tool_service = None

I have also disabled TypingIndicator in host_agent_server.py as it is a bit noisy and suffers from the same error:

+       self.agent_app.options.start_typing_timer = False
        self.agent_notification = AgentNotification(self.agent_app)
        self._setup_handlers()

For ChatClient, I replaced AzureOpenAIChatClient with a dummy ChatClient:

class CustomChatClient:
    @property
    def additional_properties(self) -> dict[str, any]:
        return {}

    async def get_response(self, messages, **kwargs):
        return ChatResponse(
            messages=[ChatMessage(role="assistant", text="this is a generic response")],
            response_id="custom",
        )

    def get_streaming_response(self, messages, **kwargs):
        async def _stream():
            from agent_framework import ChatResponseUpdate

            yield ChatResponseUpdate()

        return _stream()

In .env.sample there isn't a CONNECTIONS__SERVICE_CONNECTION__SETTINGS__CLIENTID but it seems to be required. I set it to our client ID.

I am testing by sending the Agent user in my directory an email from Outlook. I am able to see my service receiving this event and mostly processed correctly by the agent in the sample project.

The above error happens when it attempts to send back a response.

I have also tested by building wheels from main off this repository and still gets the same error.

Please let me know if there is anything I can do / missing / misconfigured on my end. Appreciate any help. Thanks!

Hi @fanzeyi , thanks for reporting this. It looks like you're hitting an issue with the sample implementation where the response to an email notification was not handled correctly. We have opened a PR to address this: microsoft/Agent365-Samples#109
Can you please try it out and see if that resolves the issue?

[pontemonti]

Closing this issue since the sample code has been updated. Please open a new issue if you are still facing issues. Thanks!
