Checking the stack trace pasted - it looks like the bug is being thrown on Botbuilder? Do you have a screenshot/video of the bug? Looks like there's no text associated with the activity from quick glance

[frankqianms]

@lilyydu Added a repro video and linked issue added in botbuilder repo.

I can reproduce this error. This only happens when the 'bot' is invoked via M365 Copilot (Custom Engine Agents), not when the bot is invoked directly in Teams.

When I removed the code that is at fault, the initial error is gone, but it still wont work. No activity is being broadcasted to the Custom Engine bot.

This looks like it was fixed on Botbuilder via microsoft/botbuilder-python#2216 - closing
