Uncaught TypeError: Cannot set property 'length' of undefined

See original GitHub issue

Hi thanks for this addon. I’m getting this error with remote pagination.

versions:

ember-cli-pagination: 3.1.3
ember: 3.4.1
ember-data: 3.4.2

route:

import Route from '@ember/routing/route';
import { hash } from 'rsvp';
import RouteMixin from 'ember-cli-pagination/remote/route-mixin';

export default Route.extend(RouteMixin, {
  model(params){
    return hash({
      tracks: this.findPaged('track', params),
      labels: this.store.findAll('label')
    });
  }
});

api response for tracks:

I too am experiencing this issue.

I have just found this problem after upgrade to 3.5 as well. I’ve been debugging it for some time and I think the main issue is that init method of PagedRemoteArray is not calling this._super(...arguments). Once I added it it’s working again.

I may create a PR but this project doesn’t seem to be very active recently.
