Assertion Failed: Attempting to inject an unknown injection: 'service:session'

I have an EmberJS app, where for one of my controllers I'm getting an error Assertion Failed: Attempting to inject an unknown injection: 'service:session'

I'm using a session service that utilizes the library ember-simple-auth. I have used the session service so I know that it works, but I am still getting this error? Does it have anything to do with any of the node ember modules being updated ?

Controller

import Controller from '@ember/controller';
import { get, set } from '@ember/object';
import $ from 'jquery';
import config from '../../../config/environment';
import { inject as service } from '@ember/service';

export default Controller.extend({
  session: service('session'),
  actions: {
    merge(preserve) {
      let ExpList = [];

      // To-Do Make this a computed property
      get(this, 'model.experiences').forEach(function(exp) {
        ExpList.pushObject(exp.id);
      });

      this.get('session').authorize('authorizer:django', (authKey, authToken) => {

        $.ajax({
          url: `${config.APP.API_HOST}/api/v0.1/`,
          type: 'POST',
          headers: {
            'Authorization': authToken
          },
          data: {
            'experience_ids': ExpList,
            'name': get(this, 'model.newExp.name'),
            preserve,
            'module': get(this, 'moduleExp')
          }
        }).then(() => {
          this.transitionToRoute('route');
        }).catch(function(error) {
          this.set('errorMessage', error.error || error);
        });

      });
    }
  }
});
