请告诉我如何使用 SSR Angular Universal 在第 404 页上提供 http 代码 404。Angular 7 版本的代码不起作用，给出了很多无穷无尽的错误。代码如下所示。

//Код компонента страницы 404 (notfound.component.ts)

import {Component, Inject, OnInit, Optional, PLATFORM_ID} from '@angular/core';
import {RESPONSE} from '@nguniversal/express-engine/tokens';
import {isPlatformServer} from '@angular/common';
import { Global } from '../core/global'

@Component({
  selector: 'app-not-found',
  templateUrl: './not-found.component.html',
  styleUrls: ['./not-found.component.css']
})
export class NotFoundComponent implements OnInit {

  constructor(
    public global: Global,
    @Inject(PLATFORM_ID) private platformId: Object,
    @Optional() @Inject(RESPONSE) private response,
  ) {}

  ngOnInit() {
    if (isPlatformServer(this.platformId)) {
      this.response.status(404);
    }
  }

}

//Часть кода в файле server.ts

import {REQUEST, RESPONSE} from '@nguniversal/express-engine/tokens';

app.get('*', (req, res) => {
  res.render('index', { 
    req,
    providers: [
      {
        provide: RESPONSE,
        useValue: res
      }
    ]
   });
});

ps如果对如何实现代码的返回有其他的想法和建议，我会很乐意提出建议）
