sendEmailVerification() - Cannot assign to read only property '_canInitEmulator

Hi, I’ve spent so much time without finding the answer so I assume it could be a bug. After creation of a new user by createUserWithEmailAndPassword() I’m calling current user from AngularFireAuth instance. Then I call sendEmailVerification() which causes an error:

TypeError: Cannot assign to read only property '_canInitEmulator' of object '[object Object]'

    at _performFetchWithErrorHandling (index-839de510.js:936)

It happens for angular 12 and 13. Angular: 13.1.0 Firebase: 9.4.0 Angularfire: 7.2.0

I didn’t see your code, but probably the error occurs when you pass User object (which you get from calling createUserWithEmailAndPassword) to signupSucces. I had the same problem and I solved it as suggested in this thread: signout function in ngrx effect with() #3251

So I created an interface for user details like this to avoid using User interface from firebase:

interface UserInfo {
  displayName: string | null;
  email: string | null;
  phoneNumber: string | null;
  photoURL: string | null;
  providerId: string;
  uid: string;
}

I added also User parsing method

const parseUser = ({
  displayName,
  email,
  phoneNumber,
  photoURL,
  providerId,
  uid,
}: User): UserInfo => ({
  displayName,
  email,
  phoneNumber,
  photoURL,
  providerId,
  uid,
});

And finally my signup effects look like this:

signup$ = createEffect(() =>
  this.actions$.pipe(
    ofType(AuthActions.authSignupActions.start_signup),
    switchMap(({ signupCredentials }) =>
      this.authService.signupUser$(signupCredentials).pipe(map(parseUser))
    ),
    map(() => AuthActions.authSignupActions.done_signup({ user }))
  )
);

@artask @Sapython provideAuth was added during automatically installation so there’s no thing I could change at my code.
