Я пытаюсь получить имя друга пользователя с помощью Spring Social Facebook. Список друзей = facebook.friendOperations().getFriendProfiles(); Это утверждение дает мне ошибку 400 Bad Request.
@Controller
@RequestMapping("/")
public class HelloController {
private Facebook facebook;
@Inject
public HelloController(Facebook facebook) {
this.facebook = facebook;
}
@RequestMapping(method=RequestMethod.GET)
public String helloFacebook(Model model) {
if (!facebook.isAuthorized()) {
return "redirect:/connect/facebook";
}
model.addAttribute(facebook.userOperations().getUserProfile());
System.out.println(facebook.userOperations().getUserProfile().getName());
System.out.println(facebook.userOperations().getUserProfile().getEmail());
//PagedList<FacebookProfile> fbFrnds = facebook.friendOperations().getFriendProfiles();
List<String> friendIds = facebook.friendOperations().getFriendIds();
System.out.println("Id size : "+friendIds.size());
List<FacebookProfile> friends = facebook.friendOperations().getFriendProfiles();
System.out.println("Size : "+friends.size());
for (FacebookProfile id : friends) {
System.out.println(id.getName());
}
return "hello";
}
}

Я дал следующее разрешение в разделе «Настройка разрешений центра приложений». 
Любая идея, почему это происходит? Заранее спасибо.
