Simple-Auth: Trouble getting started

Question

I am having trouble following SimpLabs' starting guide for ember-simple-auth.

Following the guides on the home page, word for word, does not work.

When I test my login form, the "authenticate" action goes up to the controller and errors.

Is there an extra step that the website forgot to mention? I feel like I have checked and rechecked everything...
