I am facing difficulties retrieving the JSON object returned from the Express GET route in Angular

After setting up an express route, the following JSON is returned:

[{"_id":"573da7305af4c74002790733","postcode":"nr22ry","firstlineofaddress":"20 high house avenue","tenancynumber":"12454663","role":"operative","association":"company","hash":"b6ba35492f3f83a79395386cfc601178dfd11de723d2007daf6bd34160a9ff16c87b1f07835e7a39c20454c6271960930211b365ae05c620809c159a3d7b97de","salt":"8d544f21c436494da859cf5895c414d9","username":"yhy","__v":0}]

Inside my Angular app, there is a factory with the code below:

auth.userRole = function() {
   alert('here');
   if (auth.isLoggedIn()){
          return $http.get('/roles/' + auth.currentUser(), {
headers: {Authorization: 'Bearer '+auth.getToken()}
  }).then(function(response){          
    //the info is here, i just can't get to it!!!

    return response;          
  });   
   }
};

This factory method is called in the controller like so:

$scope.therole = auth.userRole(); 

The view displays the user role as:

user role is: {{ therole }}

Despite being able to see the JSON response when debugging in Chrome console, I'm unable to access it properly. Various attempts such as returning response.data or response.data.role have been unsuccessful, resulting in either blank output or 'property not defined error'. It seems like a simple issue, but I must be missing something obvious. Any help would be greatly appreciated!

Successfully resolved my own issue with the following solution:

   auth.theUserInfo = function() {
   if (auth.isLoggedIn()){
          return $http.get('/roles/' + auth.currentUser(), {
headers: {Authorization: 'Bearer '+auth.getToken()}
 }).then(function(response){          
    //the info is here, i just can't get to it!!!

    return response.data[0];
  });   
   }
};

The data returned by response.data[0] contains the entire object.

Upon further investigation, I discovered that the problem was in my controller. I had mistakenly assumed that by assigning the return value of the function to a variable, it would pass the value back immediately. However, due to the asynchronous nature of the function, I could not make that assumption. To address this issue, I modified the code as follows:

auth.theUserInfo().then(function(data) {
   $scope.therole = data.role; 

});

This updated approach now functions correctly! Additionally, since my (now renamed) theUserInfo function returns the entire object, not just the role, I have the potential to reuse it elsewhere in my controller.
