assert.js:36 Mirage: Your Ember app tried to POST '/users/sign_in',
but there was no route defined to handle this request. Define a route
that matches this path in your mirage/config.js file. Did you forget
to add your namespace?
I allow all requests to localhost:3000/api/v1 to passthrough so mirage isn’t an issue with most requests.
However, I am not sure where my app is making this POST request to. Is it localhost:4200?
Does my server need to have a /users/sign_in endpoint? And if so, does it need to handle this request somehow? I feel like that should be built in to ember-simple-auth since that’s kind of the point of using a 3rd party for this sort of thing.
