Web socket client shuts down with RSV value errors

[n-srinidhi]

Hi! I have an autobahn web socket client and a Web socket server (Written in c#). Whilst receiving packets encoded using UTF-8 encoding, I am getting errors while decoding the payload and my web socket client shuts down.

Code:

def onMessage(self, payload, isBinary):
     _message=payload.decode('utf8')

Socket Client shuts down with following information:

WebSocket connection closed: connection was closed uncleanly ("I dropped the WebSocket TCP connection: RSV = 2 and no extension negotiated") WasClean False Code 1006

Sometimes it also exits with RSV codes 3 and 7. Can anyone help with what could be the issue? I've been combing the docs but haven't made progress.

Exception:
ERROR: [2024-04-16 13:27:44,178] ['Traceback (most recent call last):\n', ' File "<frozen centra_server>", line 71, in onMessage\n', "UnicodeDecodeError: 'utf-8' codec can't decode byte 0x82 in position 2087508: invalid start byte\n"]

Can anyone help with what could be the issue?

most likely, the websocket server you are using has bugs. I would recommend checking the websocket server using

https://github.com/crossbario/autobahn-testsuite

this can be done without writing any code.

unless & until all tests return green there, it doesn't make sense to hunt for any AutobahnPython or user code issues ..
