The problem with the AJAX request

I have a strange problem with the AJAX request to the remote server. If I make a request through POSTMAN, then I get a response with a nested array.

{
    "id": "n254",
    "created": "2017-10-02T11:50:29+0200",
    "modified": "2017-10-09T14:19:15+0200",
    "status": true,
    "town_id": 16,
    "image": "pic.jpg",
    "image_dir": "img",
    "wp_id": "5312",
    "newsdescriptions": [
        {
            "id": 419,
            "name": "Name",
            "description_short": "Description short",
            "description_long": "<p>Description long</p>",
            "new_id": 254,
            "language_id": 2,
            "created": "2017-10-02T11:50:29+0200",
            "modified": "2017-10-05T12:07:04+0200"
        }
    ],
    "type": "new",
    "image_url": "https://192.168.1.102/img/news/image/pic.jpg"
}

But if I make a request from an application, I get a response from the application without a nested array.

{
    "id": "n254",
    "created": "2017-10-02T11:50:29+0200",
    "modified": "2017-10-09T14:19:15+0200",
    "status": true,
    "town_id": 16,
    "image": "pic.jpg",
    "image_dir": "img",
    "wp_id": "5312",
    "newsdescriptions": [],
    "type": "new",
    "image_url": "https://192.168.1.102/img/news/image/pic.jpg"
}

The code that makes the request:

$http({
      url: ApiEndpoint.url + '/news/selectNew/' + params.townhallId + '/' + params.langId + '/' + params.id,
      method: 'GET',
      cache: false,
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'User': 'user',
        'Password': 'pass'
      }
    }).then( function(data) {
      console.log("URL Ajax:");
      console.log(ApiEndpoint.url + '/news/selectNew/' + params.townId + '/' + params.langId + '/' + params.id);
      console.log("Data:");
      console.log(data.data);
      callback(data.data);
    }, function(data) {
      console.log('getNew: ajax error!');
    });

Help please solve this problem!
