Angular 8 Ошибка HttpTestingController - 'Cannot flu sh отмененный запрос.'

Question

У меня реальная проблема с моим тестом, в то время как HTTP-вызов, который я успешно работал, смоделировал и возвратил, теперь не сбрасывается из теста и вызывает сбой теста. Я получаю сообщение об ошибке:

Cannot flush a cancelled request.

Сам по себе тест использует Jest / Cucumber в рамках среды тестирования по умолчанию, и все это работает правильно, поэтому проблема не возникает *

Часть «тогда» в моем тесте выглядит следующим образом:

then(
      /^the payment authority should be sent as '(.*?)'$/,
      fakeAsync(consent => {
        tick();
        flushBrandPropertyCall(httpTestingController);
        flushQuoteStatusCall(httpTestingController);
        flushReferenceDataCall(httpTestingController);
        httpTestingController.verify(); //Similar to an assert just make sure page is stable before continuing

        const submitBtn = fixture.debugElement.query(By.css('#continue-button')).nativeElement;
        submitBtn.click();

        const timeRequest = httpTestingController.expectOne(HttpUrl.Time);
        console.log('Cancelled?', timeRequest.cancelled);
        if (!timeRequest.cancelled) timeRequest.flush({ now: Date.now() });
        flushBrandPropertyCall(httpTestingController);
        tick(1500); // Not sure exact source - maybe modal messages?
        const payRequest = httpTestingController.expectOne(HttpUrl.SinglePayment);
        expect(payRequest.request.body.paymentAuthority).toEqual(consent);
        payRequest.flush({ paymentStatus: 'CARD_PAYMENT_SUCCESS', authCode: '', policyNumber: 5555, quoteVersion: 20 });
        httpTestingController.verify();
        expect(true).toEqual(true);
      })
    );
  });

И отменяется неудачный HTTP-вызов flushBrandPropertyCall), который выглядит следующим образом:

export const flushBrandPropertyCall = (controller: HttpTestingController) => {
  const request = controller.expectOne('/web-services/rest/properties/removedForSecurity');
  console.log(request)

  request.flush([

Я пытался посмотреть онлайн, но не могу найти информацию об этой ошибке. Кто-нибудь знает, почему запрос будет отменен из тестовой спецификации c с использованием HttpTestingController?

Я также console.logged requestOne и вот объект запроса
