MongoDB使用聚合$facet报错

Question

查询条件如下

db.doc_user_orders.aggregate([
  {
        $match: {
            "orgGroup": "汽车事业群"
        }
    },
    {
        $facet: {
            "data": [
                
                {
                    $sort: {
                        "_id": -1
                    }
                },
                {
                    $skip: 0
                },
                {
                    $limit: 10
                }
            ],
            "total": [
                
                {
                    $count: "total"
                }
            ]
        }
    }
])

报错如下：

assert: command failed: {
    "ok" : 0,
    "errmsg" : "Unrecognized pipeline stage name: '$facet'",
    "code" : 16436
} : aggregate failed

这个是什么原因？

写的没问题啊, facet是3.4以上的, 版本不对?
