Active Model Serializers not compatible with currentUser

[alereisan]

I am using Active Model Serializers Gem and have created an UserSerializer (users_serializers.rb). Since then I cannot access Auth.currentUser() in AngularJS anymore. Everything else (Login/Reg/Oauth) still works... When I remove the UserSerializer Auth.currentUser() is accessible again...

Is there a fix for this issue, or am I just missing something?

My UserSerializer, which causes the Problem with Auth.currentUser() looks like this:

class UserSerializer < ActiveModel::Serializer
  attributes :id, :email, :created_at, :updated_at, :username, :provider, :uid, :name, :photo

  has_many :auctions
end

JSON Output with UserSerializer disabled:

{"id":1,"email":"[email protected]","created_at":"2015-10-28T18:21:56.944Z","updated_at":"2015-10-31T14:06:25.846Z","username":"MuteMinute","provider":"facebook","uid":"1***5","name":"Alessandro Santamaria","photo":"http://graph.facebook.com/1***5/picture"}

JSON Output with UserSerializer enabled (includes the auction model):

AngularJS Controller for Auth (navCtrl):

  $scope.signedIn = Auth.isAuthenticated;

  $scope.logout = Auth.logout;

  Auth.currentUser().then(function(user){
    $scope.user = user;
  });

  $scope.$on('devise:new-registration', function (e, user){
    $scope.user = user;
  });

  $scope.$on('devise:login', function (e, user){
    $scope.user = user;
  });

  $scope. $on('devise:logout', function (e, user){
    $scope.user = {};
  });
