Web Socket Error 0


I’m subscribe klines in web socket in wss://stream.binance.com:9443/ws but i’m receiving error 0 in some symbols.
Error 2023-05-01 09:57:57 REEFUSDT 5m: 0
Error 2023-05-01 09:57:57 PERPUSDT 5m: 0
Error 2023-05-01 09:58:20 ARUSDT 5m: 0
Error 2023-05-01 09:58:26 CELRUSDT 5m: 0

This is the code:
ws = websocket.WebSocketApp( “wss://stream.binance.com:9443/ws”,
on_message = self.on_message,
on_error = self.on_error,
on_close = self.on_close,
on_open = self.on_open)

    subscribe = {

Anyone knows why?

There’s no problem using
websocat -v "wss://stream.binance.com:9443/ws/perpusdt@kline_5m"

So the problem is at your local code, maybe with the used library? Try to print more information at the on_error to debug the situation.
