WebSocket is closed right after connection

[Kayrrhan]

I tried to use NativeWebSocket in Unity to communicate with a python server, which is based on Flask Socket IO.

I used the sample in the readme file just to try simple communication and when launching my app, the websocket is instantly closed after connection is done. I tried to investigate with the debugger tool and found out the issue might come from the Receive() method in WebSocket.cs :

result = await m_Socket.ReceiveAsync(buffer, m_CancellationToken);

Even though m_CancellationToken is set to false, after this instruction is done, my websocket state changes from 'Open' to 'CloseReceived' which leads to, as said, the closure of the websocket.

Did I miss anything in the setup of the NativeWebSocket or is this some kind of unwanted behavior out of scope?
