Error: Attempting to access 'defer' property of an undefined object in Angular JS WebSocket

I am relatively new to the world of web technologies, piecing together code snippets from various sources to create this code.

My task involves retrieving data for a web application built on angularjs from a websocket using APIs.

Below is the code snippet:

 angular.module("MyApp")
       .service("myService", function ($rootScope, $q) {
           // Code here...
       });

Upon opening my web app for the first time, I encounter an error 

"Uncaught TypeError: Cannot read property 'defer' of undefined at Websocket"
. Could someone provide guidance on resolving this issue?

Answer №1

Figured it out on my own by making the necessary code adjustments. Here's what I did:

 if(replyId >= 0){
       $rootScope.$apply(histItem.defer.resolve(asJson.result))                        
      }
