Using custom authenticator with ember-simple-auth and promises returning undefined for resolve

I am using Ember.js and ember-simple-auth.

I have a custom authenticator named apps\authenticators\jwt.js with a method called authenticate:

  authenticate(credentials) {
    const { identification, password, secret } = credentials;

    const data = JSON.stringify({
      name: identification,
      password: password,
      secret: secret
    });

    const requestOptions = {
      async: true,
      crossDomain: true,
      url: 'https://website.com/api/auth/login',
      processData: false,
      method: 'POST',
      contentType: 'application/json',
      data: data,
    };

    return new Promise(function(resolve, reject) {
      Ember.$.ajax(requestOptions).then(function(data) {
        Ember.run(null, resolve, data);
        console.log(data); 
      }, function(jqXHR , textStatus, errorThrown) {
        jqXHR.then = null;
        Ember.run(null, reject, jqXHR, textStatus, errorThrown);
      });
    });
  },

and the controller for my login.hbs template:

import Ember from 'ember';

export default Ember.Controller.extend({
  session: Ember.inject.service('session'),

  actions: {
    authenticate() {
      var credentials = this.getProperties('identification', 'password', 'secret'),
      authenticator = 'authenticator:jwt';

      this.getProperties('identification', 'password', 'secret');
      this.get('session').authenticate(authenticator, credentials).then(function(result) {
        console.log(result);
      }, function(err) {
        console.log(err);
      });
    }
  }
});

If I successfully fill out the form and submit it I get a status code 200 and the proper response from the server from the line console.log(data); in the authenticate method in jwt.js But the line console.log(result); in the controller returns undefined.

However, if I fail to fill the form out and submit it I get the proper response from the server from the authenticate method AND I get that message from the console.log() in the controller.

My goal is to get the response on success to the template.

I can't seem to figure out why this is happening, any help is appreciated.

Edit: I am able to achieve my goal using localStorage however I would like to figure out the issue with the promise.

Edit 2: When I check the console, I get undefined first, then the data from console.log(data). Is the issue the order in which they're being executed asynchronously?

Edit 3: Here is my config/environment.js file

/* jshint node: true */

module.exports = function(environment) {
  var ENV = {
    modulePrefix: 'alpha',
    podModulePrefix: 'alpha/pods',
    environment: environment,
    rootURL: '/',
    locationType: 'auto',
    EmberENV: {
      FEATURES: {
        // Here you can enable experimental features on an ember canary build
        // e.g. 'with-controller': true
      },
      EXTEND_PROTOTYPES: {
        // Prevent Ember Data from overriding Date.parse.
        Date: false
      }
    },

    APP: {
      // Here you can pass flags/options to your application instance
      // when it is created
    }
  };

  ENV['ember-simple-auth'] = {
    authorizer: 'authorizer:session'
  };

  if (environment === 'development') {
    // ENV.APP.LOG_RESOLVER = true;
    // ENV.APP.LOG_ACTIVE_GENERATION = true;
    // ENV.APP.LOG_TRANSITIONS = true;
    // ENV.APP.LOG_TRANSITIONS_INTERNAL = true;
    // ENV.APP.LOG_VIEW_LOOKUPS = true;
  }

  if (environment === 'test') {
    // Testem prefers this...
    ENV.locationType = 'none';

    // keep test console output quieter
    ENV.APP.LOG_ACTIVE_GENERATION = false;
    ENV.APP.LOG_VIEW_LOOKUPS = false;

    ENV.APP.rootElement = '#ember-testing';
  }

  if (environment === 'production') {

  }

  return ENV;
};
