mongoose怎么比较时间？

Question

checkSession: function (ownSessionKey, cb) {
        const now = moment().toISOString();
        console.log(now);
        sessionModel.find({sessionKey: ownSessionKey}, {expireTime: {"$gte": now}}, function (err, docs) {
            if (err) console.log("错误: " + err);
            console.log('查询结果：' + docs);
            cb(docs);
        })
    }

这段代码怎么会报这个错？错误: MongoError: Unsupported projection option: expireTime: { $gte: "2017-05-23T10:18:05.165Z" },感觉格式都正确着呢。

我写错格式了, 应该是这样：

checkSession: function (ownSessionKey, cb) {
        const now = moment().toISOString();
        console.log(now);
        sessionModel.find({sessionKey: ownSessionKey, expireTime: {"$gte": now}}, function (err, docs) {
            if (err) console.log("错误: " + err);
            console.log('查询结果：' + docs);
            cb(docs);
        })
    }
