Error Nothing handled the action 'sessionInvalidationSucceeded' using Simple Auth Ember JS

So I have been setting up a auth manager through my ember for the past week a and finally got it working. However, I'm still getting a error when invalidating the user.

Nothing handled the action 'sessionInvalidationSucceeded'

Can't figure out what the best way to handle the error?

import Ember from 'ember';
import DS from 'ember-data';

export default Ember.Object.extend({
 authenticate: function(controller, user) {
  var app = this.container.lookup('controller:application');
  var session = app.get('session').authenticate('simple-auth-authenticator:oauth2-password-grant', user);
  session.then(function() {
    console.log('Session Started');
    controller.transitionToRoute('brands');
  });
 },
 endSession: function() {
  var app = this.container.lookup('controller:application');
  var session = app.get('session').invalidate();
  session.then(function() {
   app.store = DS.Store.create();
   console.log('Session Ended');
   app.transitionToRoute('index');
   app.store.destroy();
  });
 }
});


import Ember from 'ember';

export default Ember.Controller.extend({
 actions: {
   sessionEnded: function() {
    this.authManagerService.endSession();   
   }
 },
 currentUser: function() {
  return this.store.find('user', this.session.get('user_id');
 }.property('@each.user')
});
