If using python 3.11, python client would return this error
TypeError: BaseEventLoop.create_connection() got an unexpected keyword argument 'extra_headers'
Due to the incompatibility to current websockets library version

Daniel mentioned that he needs the websocket module to be at least 15.0 so that he can use the decode setting in recv

        buff = await websocket.recv(decode=False)
        data=buff.decode(encoding='UTF-8',errors='ignore')
