[🐛] Auth createUserWithEmailAndPassword always returns `Cannot read property 'code' of undefined` on Android

[thevishnupradeep]

Issue

Attempting to register a user using createUserWithEmailAndPassword within an expo application consistently results in a TypeError when accessing the code property of the caught error object, specifically: [TypeError: Cannot read property 'code' of undefined]. The problem only occurs on android and I can confirm that iOS works fine.

Hi there I was not able to reproduce this bug. I ran this locally with my expo app on Android, setup my registering as so:

export class AuthService {
  async registerUser(email: string, password: string) {
    try {
      const res = await createUserWithEmailAndPassword(getAuth(), email, password);
      console.log('Response @ ', res);
      return res;
    } catch (e) {
      console.log('error @ createUserWithEmailAndPassword: ', e);
      const error = e as FirebaseAuthTypes.NativeFirebaseAuthError;
      if (error.code === 'auth/invalid-email') {
        throw new Error('Invalid email address');
      }
      else if (error.code === 'auth/email-already-in-use') {
        throw new Error('Email address already in use. Try signing in.');
      }
      else if (error.code === 'auth/weak-password') {
        throw new Error('Password is too weak. Try a stronger password.');
      }
      else {
        throw new Error('An error occurred. Please try again later.');
      }
    }
  }
}

Then ran this through the function you presented here and it worked fine. Could you compare our implementations or even send me what you have?
