Angular - Importing O which does not have a ɵmod property

I am configuring jest for my Angular application.

I put all imports and providers in two seperate arrays and then imported the arrays as follows. Then I provide these arrays as the respective providers and imports for TestBed.

import { imports } from 'app.imports';
import { providers } from 'app.providers';

beforeEach(() => {
TestBed.configureTestingModule({
  declarations: [ SamplePage ],
  imports: imports,
  providers: providers
}).compileComponents();

I have several test files which give the following error on running npm test

FAIL  src/app/modules/sample/sample.page.spec.ts
● SamplePage › should create
