ERROR in Cannot read property 'map' of undefined

Desired behavior

Should build normaly or show me some useful output.

Mention any other details that might be useful (optional)

I’ve updated from ng5 to ng6 rc last week.

Fixed by removing the import { Request } from 'express'; in line 4 from:

import { Component, Inject, PLATFORM_ID, Optional, OnInit } from '@angular/core';
import { isPlatformServer } from '@angular/common';
import { REQUEST, RESPONSE } from '@nguniversal/express-engine/tokens';
import { /* Request, */ Response } from 'express';

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

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

    /**
     * Life-cycle hook.
     */
    ngOnInit() {
        if (isPlatformServer(this.platformId)) {
            this.response.sendStatus(404);
        } else {
            console.log('We\'r running on the browser, here\'s the RESPONSE.', this.response);
        }
    }
}

This was not an Angular issue. This just used to work with ng5 compiler.
