Error in revokeTokenWithAuthorizationCode in Apple login

[amankr]

I am trying to revoke apple token before deleting user profile in my firebase app running on Iphone 14 Pro, but is it throwing me error on FirebaseAuth.instance.revokeTokenWithAuthorizationCode(authCode)

This is the exact error I am getting

 code :  invalid-credential
 message: An internal error has occurred, print and inspect the error details for more information.

Below is the code snippet which throws me error :

final appleProvider = AppleAuthProvider();
final credential = await user.reauthenticateWithProvider(appleProvider);
final authCode = credential.additionalUserInfo?.authorizationCode;
if (authCode == null) {
  throw Error("Apple auth code not found");
}
await FirebaseAuth.instance.revokeTokenWithAuthorizationCode(authCode);

Library versions used:

firebase_core: ^3.1.0
firebase_auth: ^5.1.2

firebase server has a problem :/

I am getting the same issue with the following code:

final rawNonce = generateNonce();
  final nonce = sha256ofString(rawNonce);

  final AuthorizationCredentialAppleID credential;
  try {
    credential = await SignInWithApple.getAppleIDCredential(
      scopes: [
        AppleIDAuthorizationScopes.email,
        AppleIDAuthorizationScopes.fullName,
      ],
      nonce: nonce,
    );
  } catch (e) {
    print(e);
    return null;
  }

  // Create an `OAuthCredential` from the credential returned by Apple.
  final oauthCredential = OAuthProvider("apple.com").credential(
    idToken: credential.identityToken,
    rawNonce: rawNonce,
  );
  
  await FirebaseAuth.instance.signInWithCredential(oauthCredential);
  
  if (credential == null) {
  // Failed to re-sign-in
    return;
  }
  try {
    FirebaseAuth.instance.currentUser.reauthenticateWithCredential(credential)
    await FirebaseAuth.instance
        .revokeTokenWithAuthorizationCode(
        credential.authorizationCode);
  } catch (e) {
    print(e);
    return;
  }

I'm running into the same problem!
Except the error message is says the "[firebase_auth/invalid-credential] Error getting access token from Apple. OAuth2 redirect uri is".

Did I not configure something right perhaps? @amankr @CoocooFroggy Did either of you figure out what was wrong?

@zakton5 Unfortunately I could not manage to get it working using solely Firebase auth / Flutter. I ended up going with this solution using Firebase functions.
