facebook - 通过 facebook fql 获取喜欢的照片会导致 OAuthException

Question

直到几天前，这个查询曾经给我一个我喜欢的（一些）照片的列表：

$params = array(
    'method' => 'fql.multiquery',
    'queries' => '{
        "objects" : "SELECT object_id FROM like WHERE user_id = me() LIMIT 500",                
        "likes" : "SELECT object_id, owner, src_big, src_big_width, src_big_height, link, caption, created, like_info FROM photo WHERE object_id IN (SELECT object_id FROM #objects)",
        }'
    );

现在我得到的回报是

{
  "error": {
    "message": "An unknown error has occurred.", 
    "type": "OAuthException", 
    "code": 1
  }
}

我获得的权限是 read_stream、user_likes、user_photos 和friend_photos。但是我尝试了所有可能的权限，仍然是同样的错误。有什么建议吗？
