@ryanbasiltrickett Did you happen to find a solution? Currently struggling with the same error (while running tests).

I managed to fix this problem by adding imports: [ NgxsModule.forRoot()], in TestBed.configureTestingModule

beforeEach(async () => {
    await TestBed.configureTestingModule({
      imports: [NgxsModule.forRoot()],
      declarations: [],
      providers: []
    }).compileComponents();
  });
