Get values from observable other with subscribe() methode

I have a function that retrieves values , inside it I use observable.

this.values$ = this.apiService.retrieveIndicatorHistory(this.indicatorName, this.currentPeriod)
  .pipe(
    tap(_res => console.log(`value: ${_res}`)),
    map(
      (_res: any) => {
      this.indicatorService.changeLoadingIndicator(this.indicatorName, false);
        return _res;
      }
    ),
    catchError((err: any) => {
      this.indicatorService.changeLoadingIndicator(this.indicatorName, false);
      return of(err);
    })

In the same file I have a function that needs the values returned by the observable.

 this.valuesCopy = _.cloneDeep(this.values$);

I get this error

error TS2322: Type 'Observable<any>' is not assignable to type 'any[]'.

I know that I should subscribe to the observable an retrieve values (inside retrieveIndicatorHistory function)

I would to know if is there this.values$ | async aquivalent in TS files?

Please share complete file and package.json. This is clearly a TYPE issue. You can only assign value of similar type in Typescript.

But Answer to this question can be found here. Type 'Observable<any>' is not assignable to type '[]'
