angularFire 19 upgrade crashes when deploying to production

[LanderBeeuwsaert]

This seems to be in angular/core
If we revert to firebase-js-sdk 10 and angularFire 18 the issue disappears.
It doesn't happen on our dev builds (esbuild) but it does happen when we deploy to production.
So my non-expert guess would be that treeshaking is somehow involved?

This issue does not seem to follow the issue template. Make sure you provide all the required information.

Since this is an @angular/core I'd recommend filing a bug over in https://github.com/angular/angular. Is it crashing during the SSR or CSR cycle? Node and browser versions will be helpful to debug.

[LanderBeeuwsaert]

We don't use SSR, so just "normal" CSR.
I've created a bug report in the angular repo:
angular/angular#59213
node: 22.4.0
browser: Version 131.0.6778.140 (Officiële build) (64-bits)

@jamesdaniels I have researched further but haven't been able to make a reproduction that showcases the issue.
I tried but I need to be missing something.

What I found is that it only happens if I enable optimization in angular.json
Also, the moment I comment out the subscription to AngularFire Auth authState it goes away as well

The stacktrace with sourcemaps gives:

any updates on this issue?
