ember-cli-mirage: Unable to get Mirage to intercept calls

Ember CLI: v3.11 Mirage: v1.1.0

I’m setting up an app using mirage, following these steps found in the installation guide and the overview:

1.ember install ember-cli-mirage 2. Add to config.js:

export default function() {
  this.get('/routines');
}

1. Create an ember and an ember-mirage model for routine

When making a call for all routines, in the ember Route, the model hook is used:

export default Route.extend({
  model() {
    return this.store.findAll('routine');
  },
});

When I go to the route in my app, a call is made to get routines at /routines, which the mirage config is set up to listen to. However, I get this 404 error:

Error while processing route: scenarios.index Ember Data Request GET /routines returned a 404

Instead of mirage intercepting /routines, the app is hitting http://localhost:4200/routines, which doesn’t exist for obvious reasons. I’ve tried this a few times, starting over from scratch, but I continue to have this problem. I’ve confirmed that the mirage config is loading and I haven’t made any additional setup other than what is recommended.
