failing unit test

Running this unit test:

`
import { TestBed } from '@angular/core/testing';
import { AngularFireModule } from '@angular/fire';
import { environment } from '../../../src/environments/environment';
import { AngularFireAuth, AngularFireAuthModule } from '@angular/fire/auth';

let normalUserEmail: string = 'some@test.email.com';
let normalUserPass: string = 'some_password';

describe.only('Test', () => {
beforeEach(async () => {
TestBed.configureTestingModule({
imports: [AngularFireModule.initializeApp(environment.firebaseConfig), AngularFireAuthModule],
});
await TestBed.compileComponents();
});

it('Example 1', async (done) => {
console.log('before crash');
let angularFireAuth = TestBed.inject(AngularFireAuth);
console.log('after crash');
await angularFireAuth.signInWithEmailAndPassword(normalUserEmail, normalUserPass);
done();
});
});
`

logging

Will create this error:

`
