Angular 19 SSR Build Fails with [email protected], (Resolved by Upgrading to [email protected])

[StefanKern]

Which @angular/* package(s) are the source of the bug?

Don't known / other

Is this a regression?

Yes

Description

After spending several hours troubleshooting why the SSR build was failing, it was discovered that upgrading to the latest Node.js version resolved the issue. This suggests there must be a bug when using [email protected], as Angular SSR applications do not build with this version. A bug report is being opened to address this compatibility issue.

Created app:

...>ng new angularapp
√ Which stylesheet format would you like to use? Sass (SCSS)     [ https://sass-lang.com/documentation/syntax#scss
          ]
√ Do you want to enable Server-Side Rendering (SSR) and Static Site Generation (SSG/Prerendering)? Yes
√ Would you like to use the Server Routing and App Engine APIs (Developer Preview) for this server application? No

According to https://angular.dev/reference/versions, this version should be compatible, but just isn't. It just hangs, shows building forever and does not provide any meaningful output (even with verbose).

I hope this helps someone who is stuck with a similar issue.

(used angular version: Angular CLI: 19.2.4)
