HttpClint的Observable无法从HttpResponse正确映射

我在angular7得到了服务,这给了我一些钥匙:

  getList(
    pageSize: number = 30,
    pageNumber: number = 0,
    filters: CKeyListFilters = <CKeyListFilters>{},
    sortByKey: string = 'activeTo',
    sortOrder: SortOrder = SortOrder.DESC
  ): Observable<ListPaginated<CKey[]>> {
    // ....

    return this.http
      .get<ListPaginated<CKey[]>>(`${environment.CApiUrl}/Get`, {
        params: params,
        observe: 'response',
      })
      .pipe(
        map((resp: HttpResponse<CKey[]>) => {
          return {
            content: resp.body,
            pagination: this.utilities.getPaginationMetaData(resp),
          } as ListPaginated<CKey[]>;
        }),
        catchError((error) => {
          throw error;
        })
      );
  }

但在 pipe 方法我得到此错误:

error TS2345: Argument of type 'OperatorFunction<HttpResponse<CKey[]>, ListPaginated<CKey[]>>' is not assignable to parameter of type 'OperatorFunction<HttpResponse<ListPaginated<CKey[]>>, ListPaginated<CKey[]>>'.

所以我想绘制 HttpResponse<CKey[]> 到 ListPaginated<CKey[]> 但我不知道如何才能改变它。

我继承了这个代码,我是 typescript ,所以任何建议都对我有用!
