RuntimeError: NG0203: The `EnvironmentInjector` token injection failed. Migrating Angular 18...

I updated Angular from 18 to 19 with ng update @angular/core@19 @angular/cli@19, and manually updated "@angular/core": "^18.0.5" to "@angular/fire": "19.0.0".


@NgModule({
imports: [
...
AngularFireModule.initializeApp(firebaseConfig),
AngularFirestoreModule,
...
]



@Injectable({
providedIn: 'root',
})
export class RepositoryService {
constructor(private angularFirestore: AngularFirestore) { }
