Angular promise not accurately retrieving data from JSON API

Last Updated: 02/12/2015 After reading through the comments, I discovered that the issue stemmed from an Angular module modifying the object. By using toJSON, I was able to pinpoint the problem.

I recently encountered a perplexing issue. I have a service that requests data from an API using a get request. Although the network panel in Chrome developer tools shows that the API returns the correct results, they are not displayed in the response from the Angular request.

You may notice that the content section is missing some items. Here is the relevant Angular code:

Angular Code

function getPhotos(){
      return $http.get('/photo')
        .then(getPhotosComplete)
        .catch(function(err){
         //handle errors

        });
      function getPhotosComplete(res){
        //Showing incorrect response here
        console.log("getPhotosComplete", res);
        return res.data;
      }
    }

From API

When the result of angular.toJson() appears correct, but the object displayed in the console.log is incorrect, it indicates that the object has been altered in the code after the console.log function is called.

This is because console.log initially references the object, and later converts it into a string for logging. This can lead to confusion, as it may seem like the bug exists before the console.log is executed, when in reality the problem lies after it. This can result in wasting valuable time searching through the wrong parts of the code...
