FastAPI: Error when trying to open a websocket connection after updating uvicorn

When I try to open a websocket connection to my FastAPI server, Uvicorn returns following error after I have updated it from version 0.13.4 (with this version I had no problems) to 0.15.0:

Error in opening handshake
...
websockets.legacy.handshake.check_request(headers)
AttributeError: module 'websockets' has no attribute 'legacy'

Does anyone know what this error exactly means and how to solve it?

when you update the version of unicorn then you need to update the version of websockets in my case I upgrade unicorn 0.13.4 to 0.14.0 and in the websockets version was 8.1 so I change this 8.1 to 10.0 and it's work
