Route model not rendered when using filter on route change

I'm trying to setup mirage on a new app for testing.

ember-cli: 2.16.2

ember-cli-mirage: 0.4.0

I have a dummy test, just trying to setup mirage and verify it's working. I would do something similar to test route.model(). Using mirage's JSONAPISerializer, nothing in my factory and migrage-model.

// models/trip.js
import DS from 'ember-data';

export default DS.Model.extend({
  name: DS.attr('string'),
});

My test :

import {moduleFor, test} from 'ember-qunit';
import {startMirage} from 'frontend/initializers/ember-cli-mirage';

moduleFor('route:trips.index', 'Unit | Route | trips.index', {
  needs: ['service:session', 'model:trip', 'adapter:application'],

  beforeEach() {
    this.server = startMirage();
  },

  afterEach() {
    this.server.shutdown();
  }
});

test('model', function (assert) {
  let route = this.subject();

  this.server.create('trip');

  Ember.run(() => {
    this.get('store').findAll('trip')
  });

  assert.ok(route);
});

I get this error:

TypeError: Cannot read property 'push' of null
    at Class._setupRelationshipsForModel

Works fine on development/production and using a real server to get the data.

If i dont create my record with mirage, there is no exception.

Looks like the problem only occurs within Ember.run

This will not raise the exception, but I think I need Ember.run to test properly...

test('model', function (assert) {
  let route = this.subject();

  this.server.create('trip');

  this.get('store').findAll('trip')

  assert.ok(route);
});
