Почему wall.get выдает пустые объекты java sdk vk?

try {
            GetResponse getQuery = vk.wall().get(actor)
                    .ownerId(-9165838) 
                    .offset(0)
                    .count(10)
                    .filter(WallGetFilter.ALL)
                    .execute();
            System.out.println(getQuery);
        } catch (ApiException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
