So, here is my simple GET request:

async getInspectionForm(): Promise<Observable<InspectionSummaryFormField[]>> {
let params = new HttpParams();
params = params.append('InspectionType', this.inspection.InspectionType);
params = params.append('includeInactive', 'false');

const httpComponents = await this.httpService.composeRequest('/InspectionFormCriteria', params);

return this.http.get<InspectionSummaryFormField[]>(httpComponents.fullUrl, httpComponents.httpOptions); }

Here is where I consume the result:

this.inspectionFormCritera.subscribe(formCriteria => {

  this.inspectionStorageService.inspectionFormCriteria = formCriteria;

  for(const f of formCriteria) {
    this.inspectionSummaryForm.addControl(f.FormInputName, new FormControl('', Validators.required));

    this.saveValuesOnFormChange(f.FormInputName);

    if(f.EndpointName) {
      this.dropdownFieldIterator++;
    }

    if(f.RadioSelections) {
      this.radioSelections.push(f.RadioSelections.split('-', 5)); // Because radio button selections are defined in the database like so: option1-option2-option3.
      this.inspectionStorageService.formSelections.radioSelections = this.radioSelections;
    }
  }

  this.prepareDropdownFields(formCriteria);
}, error => {
  this.newInspectionsService.inspectionDownloadTimeoutError(error);
});

However, the above use of the subscription method is deprecated in my current version of RxJS 7.5 ... So I use the preferred syntax of moving the error handler into the error: () => {} notifier function inside the subscribe call. However, my formCriteria object no longer unwraps from the observable with type InspectionSummaryFormField[], but instead with the 'any' type.

Is this just a beta issue or am I missing something important here?
