Почему wall.get выдает пустые объекты java sdk vk?

Использую Java SDK:

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();
}

Но результат всегда такой:

GetResponse{
    count=3983, 
    items=[
        WallpostFull{
            copyHistory=null,
            canEdit=null,
            createdBy=null,
            canDelete=null,
            canPin=null,
            isPinned=1,
            comments=CommentsInfo{count=0, canPost=1}, 
            likes=LikesInfo{
                count=0,
                userLikes=0,
                canLike=1,
                canPublish=1
            },
            reposts=RepostsInfo{count=0, userReposted=0}
        },
        WallpostFull{
            copyHistory=null,
            canEdit=null,
            createdBy=null,
            canDelete=null,
            canPin=null,
            isPinned=null,
            comments=CommentsInfo{count=0, canPost=1}, 
            likes=LikesInfo{
                count=0,
                userLikes=0,
                canLike=1,
                canPublish=0
            },
            reposts=RepostsInfo{count=0, userReposted=0}
        },
        WallpostFull{
            copyHistory=null,
            canEdit=1,
            createdBy=854708,
            canDelete=1,

            comments=CommentsInfo{count=0, canPost=1}, 
            likes=LikesInfo{

                canLike=1,

            },
