Challenges encountered when trying to showcase API data in Angular 6

In my application, I am making a call to the iTunes API and when I check the response, it is showing as [object object]. I believe this might have to do with the way the API's array structure is set up. I have a service injected into a component setup like this: By the way, I am using a proxy.conf.json file for the API.

service.ts

import { Injectable } from '@angular/core';
import { HttpClient, HttpEventType, HttpHeaders, HttpRequest, HttpResponse, HttpErrorResponse } from '@angular/common/http';
import { Observable, of, throwError } from 'rxjs';
import { catchError, retry } from 'rxjs/operators';

@Injectable({
  providedIn: 'root'
})
export class ApiService {

  api: string = 'api';

  constructor(
    private http: HttpClient,
  ) { }

  getAll(): Observable<any> {
    return this.http.get<any>(this.api)
      .pipe(
        catchError(this.handleError)
      );
  }
  private handleError(error: HttpErrorResponse) {
    if (error.error instanceof ErrorEvent) {
      console.log(error.error.message)
    } else {
      console.log(error.status)
    }
    return throwError(
      console.log('Something is wrong!'));
  };
}

component.ts

import { Component, OnInit } from '@angular/core';
import { HttpClient, HttpEventType, HttpHeaders, HttpRequest, HttpResponse } from '@angular/common/http';
import { ApiService } from '../../../services/api.service';

@Component({
  selector: 'app-content',
  templateUrl: './content.component.html',
  styleUrls: ['./content.component.scss']
})
export class ContentComponent implements OnInit {

  public results = [];

  constructor(private service: ApiService) { }
  private http: HttpClient
  ngOnInit() {
    this.getApi();
  }
  
  private getApi() {
    this.service.getAll().subscribe((results) => {
      console.log('JSON Response = ' + results);
    })
  }
}

API Structure

{ 
   "resultCount":50,
   "results":[ 
      { 
         "wrapperType":"track",
         "kind":"song",
         "artistId":271256
      },
   ]
}

Do you have any suggestions or insights on this issue?

To view the data in JSON format, make sure to utilize JSON.stringify method

 this.api.getData().subscribe((response) => {
      console.log('JSON Data = ' + JSON.stringify(response));
      data = response.data;
})

If you wish to loop through elements using ngFor, you can do so by

 <li *ngFor="let item of data">
      {{ item.property}}
 </li>
