domain: #"com.facebook.sdk" - code 5 error using PFFacebookUtils - ios

Question

I'm trying to retrieve Facebook user friend list using this code:
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSArray* friends = [result objectForKey:#"data"];
NSLog(#"Found: %i friends", friends.count);
for (NSDictionary<FBGraphUser>* friend in friends) {
NSLog(#"I have a friend named %# with id %#", friend.name, friend.id);
}
}];
The login as Facebook user has been implemented using parse "PFFacebookUtils"
From this tutorial https://parse.com/tutorials/login-and-signup-views
and here exactly what I've done:
1. configured my .plist file.
2. In the AppDelegate.m I've added these methods:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[Parse setApplicationId:#"your_application_id" clientKey:#"your_client_key"];
[PFFacebookUtils initializeFacebook];
}
// Facebook oauth callback
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
return [PFFacebookUtils handleOpenURL:url];
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [PFFacebookUtils handleOpenURL:url];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
// Handle an interruption during the authorization flow, such as the user clicking the home button.
[FBAppEvents activateApp];
[FBSession.activeSession handleDidBecomeActive];
}
3.In the logInViewController.m:
logInViewController.fields = PFLogInFieldsLogInButton | PFLogInFieldsUsernameAndPassword | PFLogInFieldsFacebook | PFLogInFieldsSignUpButton | PFLogInFieldsPasswordForgotten;
logInViewController.facebookPermissions = #[ #"public_profile",#"email",#"user_friends"];
I can Login successfully, but when I retrieve the user friend I get this error: (Note: I'm using test users and created a friend list for them)
Please I would appreciate any help.
