when try to connect with websocket it give a error

[wmtamit]

I use fast api and when i change version on uvicorn 0.13.4 to 0.14.0 then i getting this error

lib\site-package\uvicorn\protocols\websockets\websockets_impl.py", line 104, in process_request
    websockets.legacy.handshake.check_request(headers)
AttributeError: module 'websockets' has no attribute 'legacy'
websockets.legacy.handshake.check_request(headers)
AttributeError: module 'websockets' has no attribute 'legacy'

i attached the WebSocket initial code I use starlette.endpoints WebSocketEndpoint from starlette.endpoints import WebSocketEndpoint

for more info check here

Why I update the version because in old version not supported --ws-max-size this so please solve this as soon as possible.
if possible to increase the size of buffer request in uvicorn == 0.13.4
fastapi==0.63.0 starlette==0.13.6

you're probably on websockets 9 and you need version 10
