Ember Simple Auth login errors not displaying on page

I am following an online video tutorial that has setting up Ember Simple Auth Login. Everything works with exception to displaying login errors (i.e., 401 unauthorized) to the template. I have checked the code for typos but cannot find any.

In the controller login, I tried logging the e.errors to the console, but the console just says 'Undefined'. Though, if I just send the error object e to the log then I get the error object with the error.detail inside of it. Note: the error.detail is what I am trying to display on the login-form.hsb.

Any help is appreciated!

Controllers/login.js

import { inject as service } from '@ember/service';
import Controller from '@ember/controller';

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

    actions: {
        login(attrs) {
            this.get('session').authenticate('authenticator:jwt', {
                email: attrs.email,
                password: attrs.password
            }).then(() => {
                this.transitionToRoute('index');
            }).catch((e) => {
                this.set('errors', e.errors); // nothing is being displayed
                console.log(e.errors); // Says Undefined in the console
                console.log(e); // Display error to console
            });
        }
    }
