Ошибка маршрутизации AngularJS и Rails

Я следую учебному курсу: https://thinkster.io/angular-rails/

и когда я перейду к разделу: Интеграция Front-end с Asset Pipeline, вещи break;, сайт застревает в бесконечном цикле и продолжает повторять ту же ошибку снова и снова. Я проверил и перепроверял каждый шаг. Может кто-то помочь:

Ошибка:
