how to connect to a WebSocket

  1. SDK Version: 36.0.0
  2. Platforms(Android/iOS)

expo app won’t connect to a WebSocket, it keeps throwing " WebSocket error "

import io from  "socket.io-client" ;       
                                                                       
const SocketEndpoint = 'http://myserver.com'; 


useEffect(() => {
    tryLocalSignin();
   
        const socket = io(SocketEndpoint , {
          transports: ['websocket'],
          path: '/orders'
        });
        socket.connect(); 
        socket.on('connect', () => {
          setConnect(true);
          socket.emit('joinRoom', { merchant_reference })
          console.log("Conntected")
        });
      socket.on('connect_error', (err) => {
        console.log(err);
      });
      
     // socket.emit('joinRoom', { merchant_reference })
  }, [])

The error message I am getting is shown below
