Hello !
I successfully set up working deployment of Copilot Studio copilot with Manual authentication. I got 'Login' option, was redirected to webpage where I received code, pasted code to bot and it worked. I even added the app to MS Teams(with .zip) and it worked:

Suddenly I receive this message:
---------------------------------------------------------------------------------------------------------------------------------------
Sorry, something went wrong. Error code: SystemError. Conversation ID: 642bc33e-a49c-468c-981d-30854e7c4021. Time (UTC): 4/8/2024 8:05:28 PM.

I suppose something is wrong with Authenticate node in Sign in Topic.
Any suggestions ?
