Hello everyone,

I am seeking assistance with an issue regarding an AI Agent (built via Copilot Studio) that I deployed in Microsoft Teams 2 weeks ago and shared with a select group of users in my organization.

The Issue:
Initially, the agent functioned perfectly. However, it recently began returning the following error for approximately 30% of the users:

"Sorry, something unexpected happened. We’re looking into it. Error code: SystemError. Conversation ID: [removed for privacy] Time(UTC):"

Once a user encounters this error, the bot seems to enter a loop. If the user attempts to reset the interaction by typing basic commands like "hi" or "start over," the agent fails to respond as intended and continuously outputs the exact same error message and Conversation ID.

Troubleshooting Steps Taken:

Uninstalled and reinstalled the AI agent for the affected users.
Cleared the MS Teams application cache.

Unfortunately, neither of these steps resolved the issue.

Has anyone encountered a similar looping SystemError with their deployed agents, or are there specific configurations or logs I should review to break this error loop? Any guidance would be greatly appreciated.

Workarounds:

Until a permanent fix is implemented, the following workarounds can help:
Re-publish the agent with “Force newer version” enabled to reset the session binding.
Start a new conversation manually in Teams to bypass the corrupted session.
Minimize long session dependency and complex orchestration to reduce the likelihood of session corruption.

We want to assure you that we have highlighted this concern and raised a bug with the engineering team. They are aware of the issue and will investigate a proper resolution to prevent Teams sessions from getting stuck in the future.
