You want to use RxJS map method. For that you need to .pipe the observable stream like so:

  public postForObjecty(endpoint: any, data: any) {
    return new Promise((resolve, reject) => {
      let url = this.createBasicUrl(endpoint);
      let _data = this.arrangeData(data);
      let headers: any = new Headers()
      let token = `Bearer ${RestProvider.BEARER_TOKEN}`;
      headers.append('Authorization', token);
      this.http.post(url, _data, { headers: headers })
        .pipe(map((res: { json: () => any; }) => res.json()))
        .subscribe((data: unknown) => {
          resolve(data);
        }, (err: any) => {
          reject(err);
        });
    });
  }
