Attribute renders in HTML but console shows ctx.is undefined

Question

I have getNewsDetail() function that subscribes to an http get request. Then it stores in detailNews attribute what the function returns. The code works fine detailNews.created[0].value returns its value, however, in console I get ERROR TypeError: ctx.detailNews.created is undefined.

news.service.ts

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { environment } from 'src/environments/environment';
import { Observable } from 'rxjs';
import { INewsDetail } from '../../interfaces/news-detail';

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

  constructor(private http: HttpClient) { }

  getNewsDetail(id):Observable<INewsDetail> {
    return this.http.get(`${environment.url}`+`/node/`+id+`?_format=json`);
  }
}

news-detail.component.ts

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';
import { NewsService } from 'src/app/core/services/news/news.service';

@Component({
  selector: 'app-news-detail',
  templateUrl: './news-detail.component.html',
  styleUrls: [ './news-detail.component.scss']
})
export class NewsDetailComponent implements OnInit {
  detailNewsID: '';
  detailNews: any = {};

  constructor(
    private newsService: NewsService,
    private activatedRoute: ActivatedRoute
  ) { }

  ngOnInit(): void {
    this.activatedRoute.queryParams.subscribe(params => {
      this.detailNewsID = params.id;
    });

    this.getNewsDetail(); 
  }

  getNewsDetail() {
    this.newsService.getNewsDetail(this.detailNewsID).subscribe(news => {
      this.detailNews = news;
    });
  }
}

news-detail.component.html

{{ detailNews }} // Renders: [object Object] 
{{ detailNews.created[0].value }} // It renders the value, but console shows ERROR TypeError: ctx.detailNews.created is undefined.
