yes works in Angular 14, breaks in Angular 15

Description

I start migrating my Angular App from v14 to angular v15. My apps has full server side rendering using this package.
Once I completed the update to angular 15 and run npm start, it breaks with the following errors:

I was able to fix the error only by removing @nguniversal/express-engine package and commenting relevant usage code.
After the some debugging I was able to find the reproduction steps:

🔬 Minimal Reproduction

• ng new bug-angular15-nguniversal
• cd .\bug-angular15-nguniversal\
• ng add @nguniversal/express-engine
• Replace the app.component.ts code with the following:

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  title = 'bug-angular15-nguniversal';

  constructor(
    // @Optional() @Inject(REQUEST) private request: Request, ===> BUG HERE
    @Optional() @Inject(RESPONSE) private response: Response,
    @Inject(PLATFORM_ID) private platformId: any
  ) {}

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

By commenting the line @Optional() @Inject(REQUEST) private request: Request, it fires the bug. By uncommenting the build works correctly.

• Removing or uncommenting the line works.
• Removing the Request import works
• Breaks only when the line is commented and the Request import is present

./node_modules/express/node_modules/serve-static/index.js:18:14-37 - Error: Module not found: Error: Can't resolve 'path' in 'C:\projects\property\node_modules\express\node_modules\serve-static'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "path": require.resolve("path-browserify") }'
        - install 'path-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "path": false }

It looks like your browser build tries to bundle in some node.js specific stuff.
Try adding type to your express import.

import type { Request, Response } from 'express';

I managed to replicate this even when using the version 14.

It looks like it's caused by @ngtools/webpack where the unused import is not elided.
