OAuth2.0 Google not working

What happened?

Hi all, I am working on a flutter app and I am trying to get the sign in with google functionality working, but It doesn't seem to work and I believe there might be a bug.

I have followed the instructions from the following pages:

This is the code I am using to attempt to sign in with google:

  Future<User> signInWithGoogle() async {
    logger.d('Attempting to sign in with Google');
    try {
      final googleSignIn = GoogleSignIn();
      final googleUser = await googleSignIn.signIn();

      if (googleUser == null) {
        throw Exception('Google sign-in aborted');
      }
      final googleAuthCodeCredentials = Credentials.googleAuthCode(googleUser.serverAuthCode!);
      final currentUser = await realmApp.logIn(googleAuthCodeCredentials);
      return currentUser;
    } catch (e) {
      logger.e('Failed to sign in with Google: $e');
      throw Exception('Failed to sign in with Google: $e');
    }
  }

The line containing final googleAuthCodeCredentials = Credentials.googleAuthCode(googleUser.serverAuthCode!); executes successfully and I can see the object being created, however when the realmApp attempts to logIn with those credentials a 401 is thrown and I can see the following in MongoDB console

I have attempted the following

validated the clientId and clientSecret match
triple checked the configuration and its all as required
made sure that Google is enabled as a provider in MongoDB Atlas
tried using with and without OpenId Connect
tried using various redirectUrl's such as http://localhost:8081 or something like https://<appname>.realm.mongodb.com/api/client/v2.0/auth/callback -> the latter one was suggested by cursorAI, was not able to find any other references in the documentation.

My MongoDB Atlas setup:

The Client ID I set up in Google Console:

Repro steps

Create clientId in Google Console
Enable Google Provider in MongoDB Atlas
Add the clientId + secret in MongoDB Atlas under Google OAuth2.0
Attempt to sign in using google

As of now, the device sync is deprecated, its better to look into other options. https://www.mongodb.com/docs/atlas/device-sdks/deprecation/
