Is there any lesson or article where working with firebase for ember js is described in as much detail as possible?

Question

Ember.js

Watched this tutorial Installed emberfire
, added it to the environment.js file

contentSecurityPolicy: {
      'connect-src': "'self' wss://*.firebaseio.com https://*googleapis.com"
    },
    firebase: {
      apiKey: "AIzaSyB0NegzN8bpiwZQG9Hk1NXHpBTADV9XfqA",
      authDomain: "nodecms-c87f6.firebaseapp.com",
      databaseURL: "https://nodecms-c87f6.firebaseio.com",
      storageBucket: "nodecms-c87f6.appspot.com",
      messagingSenderId: "279451456587"
    },

Created a controller: \app\controllers\pages\add.js

addPage: function(){

      var self = this;

      var title = self.get('title');
      var description = self.get('description');

      var 
        menuLeft = self.get('menuLeft'),
        menuRight = self.get('menuRight'),
        menuTop = self.get('menuTop'),
        menuBottom = self.get('menuBottom');

      var pageNotActive = self.get('pageNotActive');

      var newPage = self.store.createRecord('page-item.add', {
        title,
        description,
        menuLeft,
        menuRight,
        menuTop,
        menuBottom,
        pageNotActive
      });

      newPage.save();
    }

Created a model: \app\models\pages\add.js

export default DS.Model.extend({
  title: DS.attr('string'),
  description: DS.attr('string'),
  menuLeft: DS.attr('boolean'),
  menuRight: DS.attr('boolean'),
  menuTop: DS.attr('boolean'),
  menuBottom: DS.attr('boolean'),
  pageNotActive: DS.attr('boolean'),
});

But in the end I get this:

How to be?

According to your screenshot with an error - maybe you need to register rights on firebase?
According to the lessons from the last thing that came across - yoember.com - there is a lot more.
