我如何从卖家那里得到所有的订单，然后按以前的日期到现在对它们进行排序？
这是我在Order.find（）函数中为所有事务得到的结果，

[
    {
        "_id": "636357777877c919bb2cfa45",
        "products": [
            {
                "productId": "636355a07877c919bb2cdfdc",
                "quantity": 1,
                "sellerId": "636355187877c919bb2cdf1f",
                "_id": "636357777877c919bb2cfa46"
            }
        ],
        "amount": 100,
        "createdAt": "2022-10-03T05:53:59.997Z",
     
    },
    {
        "_id": "636357da7877c919bb2d035f",
        "products": [
            {
                "productId": "636357387877c919bb2cf494",
                "quantity": 1,
                "sellerId": "636355187877c919bb2cdf1f",
                "_id": "636357da7877c919bb2d0360"
            }
        ],
        "amount": 100,
        "createdAt": "2022-11-03T05:55:38.858Z",
        "updatedAt": "2022-11-03T05:55:38.858Z",
        "__v": 0
    },
    {
        "_id": "636367d2407816df5f589bc6",
        "products": [
            {
                "productId": "63635acf7877c919bb2d3d95",
                "quantity": 1,
                "sellerId": "636355187877c919bb2cdf1f",
                "_id": "636367d2407816df5f589bc7"
            }
        ],
        "amount": 20,
        "createdAt": "2022-11-03T07:03:46.350Z",
    }
]

所以我想得到的是卖家在某个月的总金额，比如我这里有3个订单，其中一个是10月份的，另外两个是11月份的。
所以输出应该是。

October = 100
November = 120

我尝试了下面的代码，但收到了一个空数组
这是我的URL
您的位置：首页〉〉〉

router.get('/previousSales/:id', async (req,res) => {
    const {id} = req.params
    const date = new Date();
    const lastMonth = new Date(date.setMonth(date.getMonth() - 1));
    const previousMonth = new Date(new Date().setMonth(lastMonth.getMonth() - 1)); 

    try {
      const order = await Order.aggregate([
        {
          $match: {
            createdAt: {gte: previousMonth}, ...(id && {
              products: {$elemMatch: {id}}
            })

          }
        },
        {
          $project: {
            month: { $month: "$createdAt" },
            sales: "$amount",
          },
        },
        {
          $group: {
            _id: "$month",
            total: { $sum: "$sales" },
          },
        },
        
      ])  
      res.status(200).json(order)
    } catch (error) {
      res.status(400).json({message: error.message})
    }

  })

我忘了提到URL中的对象ID属于产品数组中的sellerId**。**
