    This is how the response looks now. Also meanwhile the new WebSocket implementation is not working at all.

    @admin I am not getting any error. But when I checked the promise is not getting resolved.

    let web_socket = new WebSocketClient({
    clientcode: "V27127",    
    jwttoken: jwtToken,
    apikey: "85hgcaVa",
    feedtype: "order_feed"
  });
  
  web_socket.connect()
    .then(() => {
        web_socket.fetchData("subscribe", "order_feed");  // ACTION_TYPE: subscribe | unsubscribe FEED_TYPE: order_feed
  
        setTimeout(function () {
            web_socket.close()
        }, 60000)
    });
  
  web_socket.on('tick', receiveTick);
  
  function receiveTick(data) {
    console.log("receiveTick:::::", data);
  }

    When I tried to remove the feed type parameter, I am not getting any error for this as well. After 60000ms I am getting a message socket closed.

    let web_socket = new WebSocketClient({
    clientcode: "N199330",    
    jwttoken: jwtToken,
    apikey: "GHfVT7N7",
    feedtype: "order_feed",
});

web_socket.connect()
    .then(() => {
        web_socket.fetchData("subscribe", "order_feed");  // ACTION_TYPE: subscribe | unsubscribe FEED_TYPE: order_feed

        setTimeout(function () {
            web_socket.close()
        }, 60000)
