Which @angular/* package(s) are the source of the bug?
platform-server
Is this a regression?
Yes
Description
The node server built by nguniversal/express-engine crashes seems to be failing to handle errors correctly.
Reproduction
- ng add @nguniversal/express-engine
- Throw an error in any async function
export class AppComponent implements OnInit {
async ngOnInit() {
throw new Error('');
}
// or
ngOnInit() {
new Promise((_, reject) => reject(''));
}
}
- Build and run the universal server (i.e.
npm run serve:ssr)
- The node server crashes when it tries to run the code.
The same procedure the dependencies of Angular 15 does not crash the server.
