FBSDKLoginManager works, PFFacebookUtils logInInBackgroundWithReadPermissions not

Question

I implemented the login via Facebook with parse server.

If I use this, I get user information correctly:

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login
 logInWithReadPermissions: @[@"public_profile",@"email"]
 fromViewController:self
 handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
     if (error) {
         NSLog(@"Process error");
     } else if (result.isCancelled) {
         NSLog(@"Cancelled");
     } else {
         NSLog(@"Logged in %@",result);
         [self fetchUserInfo];
     }
 }];

but I want to use PFFacebookUtils for easy user creation in Parse:

[PFFacebookUtils logInInBackgroundWithReadPermissions:@[@"public_profile",@"email"] block:^(PFUser *user, NSError *error) {
    if (!user) {
        //...
    } else if (user.isNew) {
        //...
    } else {
        //...
    }
}];

The Facebook modal appears with the authorization request, but when I press ok, I get this error:

[Error]: Facebook auth is invalid for this user. (Code: 101, Version: 1.13.0).

Inside the applications settings on Facebook, the app there.

It occurs in Parse app when the user changed Facebook password or removed your app in the applications settings on Facebook.

User.authData should be updated with PFFacebookUtils.logInInBackgroundWithReadPermissions:, but it seems to be not updated. I think that this is problem of Parse Server.

Workaround: When that error occurred, you can update User.authData with PFFacebookUtils.linkUserInBackground:withReadPermissions:.
