EmberCLI app errors when using fixtures - ember.js

Question

I usually use Rails for my Ember apps. However this time we opted to decouple the API from the Ember app, and as such I'm trying EmberCLI. So far it's lovely to setup and use. However when using attempting to use fixtures it doesn't load the data.
As listed in this post I am using reopenClass when declaring the fixtures.
If I do not override the model, it does not error but the Ember inspector also shows no data was loaded. If I override my file with:
// routes/campaigns/index.js
export default Ember.Route.extend({
model: function() {
return this.store.find('campaign');
}
});
And visit the /campaigns path then I get the error I get the error Error while loading route: undefined.
From what I can find this seems to happen when Ember cannot find the data.
My router and model with obvious items like export default excluded:
// app/router.js
Router.map(function() {
this.resource('campaigns', function() {
});
});
// models/campaign.js
var Campaign = DS.Model.extend({
name: DS.attr('string')
});
Campaign.reopenClass({
FIXTURES: [
{ "id": 1, "name": "Campaign #1" },
{ "id": 2, "name": "Campaign #2" }
]
});
I have tested the same setup in a Rails app I just made, and it works perfectly. I'd love any insight people could give, as EmberCLI seems lightweight and worth the effort.
Edit: Adding my app.js file to answer question about whether I included DS.FixtureAdapter:
// Import statements
Ember.MODEL_FACTORY_INJECTIONS = true;
var App = Ember.Application.extend({
modulePrefix: 'nala', // TODO: loaded via config
Resolver: Resolver
});
loadInitializers(App, 'nala');
App.ApplicationAdapter = DS.FixtureAdapter({});
export default App;

You need to set up your application adapter located at the filepath adapters/application.js as follows:
export default DS.FixtureAdapter.extend({});
See the first paragraph under ember-cli Naming Conventions. N.B. you won't need to import DS or Ember if you're using ember-cli and have them listed in your .jshintrc file.
