I all. I am getting this warning message from my Dagit container after it has been running for a few minutes.

dagster_dagit       | WARNING:  Unsupported upgrade request.
dagster_dagit       | WARNING:  No supported WebSocket library detected. Please use "pip install 'uvicorn[standard]'", or install 'websockets' or 'wsproto' manually.

I have tried resolving based on this SO thread: https://stackoverflow.com/questions/68828128/not-able-to-connect-to-websocket-using-nginx-and-uvicorn by uninstalling uvicorn and reinstalling uvicorn[standard] in the container entrypoint script below:

pip uninstall uvicorn --yes
pip install 'uvicorn[standard]'

# Start Dagit
exec dagit -h "0.0.0.0" -p "3000" -w workspace.yaml

However, this solution did not resolve the issue. Any ideas?
