Co-pilot chat sample app fails to invoke createChat call
Describe the bug When the webapp is launched and I log in with my Microsoft account, the createChat call returns a 400 error saying that the "ask" field is required. This is after a clean install and using an OpenAI account. The webpage then displays an error because no data has been returned. As you see in the second screenshot (webapi log), the last call fails with a 400 error when localhost:3000 is refreshed.
To Reproduce Steps to reproduce the behavior:
- Start the webapi server and ensure that it has started successfully by navigating to https://localhost:40443/probe
- Start the webapp
- Click on "sign in with Microsoft"
- Enter your credentials and click sign in
Expected behavior I'd expect to see the home page of the chat app.

@ADegitz - can you check your AppID is setup correctly in .env file. It looks like it is hitting the service, but the auth is failing. The readme has additional details that might help unblock you.
Checking back in on this - @ADegitz if you have a moment would you mind letting us know if you're still blocked here?
There have been many changes to the copilot chat sample, so I would suggest pulling the latest version before trying again.
