猫鼬总计$ match $ get $ lte日期

Question

如果请求带有startDate endDate查询，则尝试匹配日期。但是我正在使用以下方法返回空数据。

try {
    console.log(req.query.startDate);
    console.log(new Date(req.query.startDate));
    console.log(new Date(req.query.startDate).toISOString());

    let match = {};
    if (req.query.userId) {
        match.userId = req.query.userId;
    }

    if (req.query.startDate && req.query.endDate) {
        match.createdAt = {
            $gte: new Date(req.query.startDate),
            $lt: new Date(req.query.endDate)
        };
    }

    const docs = await Sale.aggregate([{
            $match: match
        }
    ]);
    return res.status(200).json({
        docs
    });
}


From console log:
