无法使日期范围的mongodb匹配在聚合内工作

我正在尝试使用match按日期范围进行筛选

这是我目前的设置：

const initReport = await Report.aggregate(
                [
                    {
                        "$lookup": {
                            from: Like.collection.name,
                            localField: "like",
                            foreignField: "_id",
                            as: "like"
                        }
                    }
                    {
                        "$lookup": {
                            from: Player.collection.name,
                            localField: "player",
                            foreignField: "_id",
                            as: "player"
                        }
                    },
                    {
                        "$unwind": {
                        path: "$player",
                        preserveNullAndEmptyArrays: true
                    }
                    },
                    {
                        "$lookup": {
                            from: Author.collection.name,
                            localField: "author",
                            foreignField: "_id",
                            as: "author"
                        }
                    },
                    {
                        "$lookup": {
                            from: Team.collection.name,
                            localField: "player.team",
                            foreignField: "_id",
                            as: "player.team"
                        }
                    },
                    {
                        "$unwind": {
                        path: "$player.team",
                        preserveNullAndEmptyArrays: true
                    }
                    },
                    {
                        "$lookup": {
                            from: League.collection.name,
                            localField: "player.team.league",
                            foreignField: "_id",
                            as: "player.team.league"
                        }
                    }
                    {
                        $match: {

                            "createdAt": {  $lte: '2020-07-23T16:37:29.710Z', $gte: '2017-07-23T16:37:29.710Z' }

                        }
                    },
                    { 
                        $group : { 
                            _id : "$_id",
                            comment: { "$first": "$comment" },
                            title: { "$first": "$title" },
                            summary: { "$first": "$summary" },
                            analysis: { "$first": "$analysis" },
                            source_title: { "$first": "$source_title" },
                            source_link: { "$first": "$source_link" },
                            author: { "$first": "$author" },
                            like: { "$first": "$like" },
                            player: { "$first": "$player" },
                            createdAt: { "$first": "$createdAt" }
                        }
                    }
                ]
            )

这将返回一个空数组

我觉得我错过了明显的，但我不确定是什么

我甚至尝试删除聚合之外的所有其他代码，除了带有日期的日期，但仍然不起作用。

在提供的代码中，

$lte

和

$gte

正在计算字符串而不是日期。如果比较日期对象，则会找到匹配项

        $match: {
        "createdAt": { $lte: new Date('2020-07-23T16:37:29.710Z'), $gte: new Date('2017-07-23T16:37:29.710Z') }
    }
