"errorMessage":"The operation couldn’t be completed. (com.google.GIDSignIn error -8.)"}

When i run my app in iOS in both of real device and simulator, Google authentication dialog is opened correctly and input my google account then submit. Google authentication is closed and I got the error below in console.

"errorMessage":"The operation couldn’t be completed. (com.google.GIDSignIn error -8.)"}

I use "@codetrix-studio/capacitor-google-auth": "^3.2.2". All settings seem to be correct.

my code is below

import { GoogleAuth } from '@codetrix-studio/capacitor-google-auth';
…
  async handleSignInClick() {
    let googleUser = await GoogleAuth.signIn();
    console.log('googleUser', googleUser);
…

Do you know why the error occur? This is my environment

After I re-build project without firebase, it works! Thanks.

I found how to reproduce this problem. When I specify https://www.googleapis.com/auth/calendar or https://www.googleapis.com/auth/drive in scope. It works at first time. But after sign out then try to sign in, this error occur in iOS.

"errorMessage":"The operation couldn’t be completed. (com.google.GIDSignIn error -8.)"}

After I disconnect my google app from my account https://myaccount.google.com/permissions?continue=https%3A%2F%2Fmyaccount.google.com%2Fsecurity Then try to sign in, it works.

This problem seems to occur when I have already passed permissions to the designated scope on my Google account on the second and subsequent logins.

I am currently using a quick workaround for this whereby if I detect the error is -8, I will use the refresh flow

GoogleAuth.refresh()

This will enable me to get the authenticationToken and the refreshToken of the user that is currently being signed in

I have the same issue in iOS With the same code, Android works fine, it is just the problem in iOS I am using the suggestion by @AlvinTCH . When I got the GIDSignIn error -8 message, I will try the refresh flow. If the refresh flow still have the problem, then I will throw the exception.

Using this logic, it works fine in my iOS app now
