Attempting to register an unknown factory in accepence test

I have a acceptance test that is failing to load an initializer during the beforeEach() application creation. Similar post here:“Attempting to register an unknown factory” in model test

Error:

tests/acceptance/home/index-test.js

import { test } from 'qunit';
import moduleForAcceptance from 'app_name/tests/helpers/module-for-acceptance';

moduleForAcceptance('Acceptance | home/index');

test('visiting /home/index', function(assert) {
  visit('/home');

  andThen(function() {
    assert.equal(currentURL(), '/account/org');
  });
});

initializers/pendo.js

export function initialize(application) {

    window.pendo_options = {
        apiKey: 'fake api key value',
        usePendoAgentAPI: true
    };

    application.register('pendo:main', window.pendo, {
        instantiate: false
    });
    application.inject('route:home', 'pendo', 'pendo:main');
    application.inject('route:home/network', 'pendo', 'pendo:main');
}

export default {
    name: 'pendo',
    initialize: initialize
};
