Websocket getting blank position

Hello,
when I am connecting through websocket getting response
{"data": "{\"positions\":[]}", "isTrusted": false} . In back-end we have devices. Any reason why i am not getting data in react native through websocket.

We don't send devices via websocket.

Hello Anton,
In browser websocket we are getting data but in react native websocket we are getting empty data. Any reason?

You are probably doing something wrong. Why would there be a difference?

Earlier same code is working but suddenly it stop working. Here is sample code :-

var socket = new WebSocket(Config.Socket_URL + '/api/socket');
      socket.onmessage = function (event) {
        console.log(event);
}

Getting response :-

{"data": "{\"positions\":[]}", "isTrusted": false}
