No supported WebSocket library detected.

I followed the instructions to run the app using Docker. The app starts up correctly, however, fails when I ask it to research something. All requirements for uvicorn[standard], websockets, and wsproto are satisfied. The error is:

Thanks for the heads up @nolandubeau

Correct this error was fixed in this commit which made it into Master 2 weeks ago

The fix was to add the websockets library to requirements.txt

Safe to close
