Displaying errors with ember DS.InvalidError

I have an ember 2.0 app that hooks up to an ASP Web API back-end. I need a way to display errors, and I know ember has built in error handling. I'm currently trying to use ember data InvalidError. I can't seem to figure out how this is supposed to work. This is my current setup

Custom adapter

export default DS.RESTAdapter.extend({
  handleResponse: function(status, headers, payload){
    if(status === 422 && payload.errors){
      console.log('working');
      return new DS.InvalidError(payload.errors);
    }
    return payload;
  }
});

My route, which inherits from a "super route", but does not affect anything going on in here at the moment.

export default superRoute.extend({
  model: function(params) {
    return this.store.query('rollup', {itemID: params.itemID});
  }
});

When I call the route I get this error

Error while processing route: rollup The adapter rejected the commit because it was invalid Error: The adapter rejected the commit because it was invalid

I've been trying to get this to work using a number of examples I have found around here. I have got this to work by setting up my controller's model through the setupController hook instead of in the model hook but I would like to not do that.
