Research direction
The error occurs in the websockets library's ClientConnection. Investigate the version of websockets used and the code that initializes the WebSocket connection. The attribute 'recv messages' might have been removed in a newer version. Check the file where the connection is created in the deer flow backend. Additionally, there are two assignees; coordinate with them before working.
