Problem with Tutorial ember recover date from mirage

Hi, I am new and I try to use Ember.js. I try to read the guide and I create the first little prototype. I have problem at a point of guide when I have to retrieve the date from mariage

The application don’t retrieve the data. Is a simple application there are only 5 file that are in the guide, I upload the application on github

Can you give a feedback. I want not escape this part of tutorial and I don’t understand the reason because the application don’t work

It looks like your app/mirage/config.js file is not returning anything:

Take a look at the tutorial again and see what needs to be included. Basically your config file will setup a fake server response.

In the future, take a look at your browser console. Are there any errors in your browser console that would have provided some guidance here?
