Ember-Cli-Mirage 404

Just followed the documentation but every time I navigate or call to the url, it returns 404 for me

// app/mirage/config.js
export default function() {

  this.get('/api/users', function() {
    return {
      users: [
        {id: 1, name: 'Zelda'},
        {id: 2, name: 'Link'},
        {id: 3, name: 'Epona'},
      ]
    }
  });

}

Uncaught UnrecognizedURLError: /api/users

Thanks for your help.
