Angular 19 doesn't generate sourcemaps for some ts files

[roma2341]

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

core

Is this a regression?

Yes

Description

Angular - 19.1.6
I noticed that its become very hard to debug code in browser, it appeared that angular doesn't build sourcemaps for some components. What is interesting is that some components have sourcemaps. I tried both chrome and firefox.

@roma2341 Could you share the angular.json settings?
I have an issue where I can't debug components, because we have aot disabled.

Thanks, i changed "aot": false to "true" and now it seems to work fine, every ts file has sourcemaps

It's very interesting because i thought that this option wasn't used by angular anymore because we can't disable aot if i understand correctly
