错误(E_VALIDATION):: 1属性无效

我试图用sails-orientdb更新一行,这样:

CommentModel.update({ _id: req.body.reply.commentId }, comment).exec(function (err, reply) { // *** LOG: LOOK BELOW console.log(comment, req.body.reply.commentId, reply); // *** if (err) return next(err); UserModel.findOne({ id: reply.author }).exec(function (err, user) { reply.author = user.toJSON(); res.json({ success: !err, reply: reply }); }); }); 

评论:{作者:'#16:0',节点:'#30:13',_id:'0dcb0fb8-35e9-4117-87e9-33e2ac21e0e0',body:'lkjnn',回复:'[object Object]', createdAt:'2015-07-21T08:50:52.000Z',updatedAt:'2015-07-21T08:50:52.000Z',id:null}

req.body.reply.commentId:0dcb0fb8-35e9-4117-87e9-33e2ac21e0e0

回覆:未定义

但是,我收到此错误消息:

错误(E_VALIDATION):: 1属性无效

请问如何解决这个问题? 怎么了?
