جاوااسکریپت - خطا: خطای شبکه: خطا در نوشتن نتیجه در فروشگاه برای پرسوجو:

این کدی است که باعث وقوع این اتفاق میشود:

   this.restaurantID$.pipe(
      takeUntil(this._ngOnDestroy)
      )
      .subscribe((restaurantID) => {
        this.additionalServicesQuery$.next(this._apollo
          .watchQuery<AdditionalServices>({
            query: AdditionalServicesQuery,
            variables: { vendorID: restaurantID }
          }));
      });

    const loadAdditionalServicesData = this.additionalServicesQuery$
      .pipe(
        takeUntil(this._ngOnDestroy),
        filter((query) => !!query),
        switchMap((query) => query.valueChanges), // This is the switchMap that makes it happen
        takeUntil(this._ngOnDestroy),
        map((response) => response.data.vendor.services.nodes)
      );

یک SwitchMap وجود دارد که من آن را کامنت کردهام، اگر آن حذف شود، خطا رخ نمیدهد. نمیتوانم بفهمم چه اتفاقی در حال رخ دادن است.

پرسوجو:

export const AdditionalServicesQuery = gql`
  query AdditionalServices(
    $vendorID: ID!
  ) {
    vendor(
      id: $vendorID
    ) {
      services: products (productTypes: service) {
        nodes {
          id
          isActive
          cartSection {
            id
            name
          }
          description
          imageUrl
          shortDescription
          name
        }
      }
    }
  }
`;

بهروزرسانی:

شناسه به پرسوجو اضافه شد، هنوز هم همان مشکل وجود دارد

export const AdditionalServicesQuery = gql`
  query AdditionalServices(
    $vendorID: ID!
  ) {
    vendor(
      id: $vendorID
    ) {
      services: products (productTypes: service) {
        id
        nodes {
          id
          isActive
          cartSection {
            id
            name
          }
          description
          imageUrl
          shortDescription
          name
        }
      }
    }
  }
`;

پاسخ شماره ۱

طبق آن خطا، شما نیاز دارید که یک فیلد id (یا فیلد _id، هر کدام موجود باشد) به مجموعه انتخاب برای فیلد vendor اضافه کنید. به نظر میرسد که شما قبلاً یک کوئری دیگر دارید که اشیاء از نوع Restaurant برمیگرداند، آن کوئری شامل id بود و بهدرستی نرمالسازی شده بود. Apollo قادر نخواهد بود اشیاء جداگانه Restaurant از هر دو کوئری را با هم ترکیب کند مگر اینکه id گنجانده شده باشد.

export const AdditionalServicesQuery = gql`
  query AdditionalServices(
    $vendorID: ID!
  ) {
    vendor(
      id: $vendorID
    ) {
      id # <----------------------------------------- ADD ME
      services: products (productTypes: service) {
        nodes {
          id
          isActive
          cartSection {
            id
            name
          }
          description
          imageUrl
          shortDescription
          name
        }
      }
    }
  }
