Connection Socket failed in release (RN 69.12)

[Tomas-caula]

Hi, I'm trying to do a Video Call app with "socket.io-client": "^4.1.2", and it's works perfectly but only in the Debug, when I make the apk my app remains blank.

useEffect(() => { if (!socketUri || !cookie) { return; } console.log('Connecting to socket', socketUri); const s = io(socketUri, { forceNew: true, withCredentials: true, transports: ['websocket', 'polling'], extraHeaders: { Cookie:token=${cookie};`,
},
});

const p = new Peer();

setSocket(s);
setPeer(p);
// establishFeed();

return () => {
  s.disconnect();
  p.destroy();
};

}, [socketUri, cookie]);`

Note: All the all permissions are required previously & android:usesCleartextTraffic="true", too

Do you get any error? Any log that could help us?

Hi, sorry for the lateness I could fix it. this happens when I run my app in the debug the connection works perfectly with this code

useEffect(() => { if (!socketUri || !cookie) { return; } console.log('Connecting to socket', socketUri); const s = io(socketUri, { forceNew: true, withCredentials: true, transports: ['websocket', 'polling'], extraHeaders: { Cookie:token=${cookie};,
},
});`

well when I try the same in the release version the data is send it different (twice) so my backend don't catch it, I just remove the extraHeaders and it's works perfectly

That's really weird. It seems that the extraHeaders option should be supported by the WebSocket implementation provided by React Native.
