ember-simple-auth: Error: Assertion Failed: The route index was not found

I am building an app with the use of ember-simple-auth.

So it looks very much like the library its doing is thing.

Here is what happens:

1. user tries to access /dashboard but is redirected to /
2. the route / contains the login form
3. the user logs in with valid credentials
4. Server responds: /token 200 0.252 ms - 52
5. But an error message is shown: Error: Assertion Failed: The route index was not found
6. user navigates to /dashboard and can now see the content, navigate around protected areas, and successfully log out.

My question is, how do I define /dashboard as the route instead of index? So that after successful login you are redirected to /dashboard

You can configure Ember Simple Auth's routeAfterAuthentication in the config, e.g.

ENV['ember-simple-auth'] = {
  routeAfterAuthentication: 'dashboard'
}
