About 33% of login cases return Error 12501

About 33% of login cases return Error 12501, which I log with Sentry.
The error is triggered by:
googlePlusUser = await this.google.login(environment.googleParams)

I have so far been unable to reproduce this issue and the error happens on all major Android versions and devices. I am using Ionic4 with Firebase and the cordova-plugin-googleplus. https://github.com/EddyVerbruggen/cordova-plugin-googleplus

Note: Already have an unanswered issue ticket there and on stack-overflow.



Currently, the app is only available on Android.

import { GooglePlus } from '@ionic-native/google-plus/ngx';

[@Injectable](https://github.com/Injectable)({
providedIn: 'root',
})
export class FirebaseAuthService {
constructor(
private google: GooglePlus,
private fireAuth: AngularFireAuth,
...
) { }

async loginGoogle(that: any): Promise {
let googlePlusUser;
try {
googlePlusUser = await this.google.login(environment.googleParams);


  return await firebase
    .auth()
    .signInWithCredential(
      firebase.auth.GoogleAuthProvider.credential(googlePlusUser.idToken)
    )
    .then((response) => {
      this.firebaseDatabaseService.saveGoogleAuthData(response.user);
      this.router.navigate(['/tabs/home']);
    })
    .catch((error) => {
      console.log('inside loginGoogle then catch: ', error);
      Sentry.captureException(error);
    });
} catch (error) {
  console.log('outside loginGoogle then catch: ', error);


Sentry.captureException(error);
}

My environment googleParams are

googleParams: { 
webClientId: 'xxx.apps.googleusercontent.com', 
offline: false, 
}

I am at a loss of what the issue is and would be happy to add any further information if requested.
