typeerror:callback.apply不是allowdiskuse之后的函数

我收藏了一百万份文件…我已经通过了 allowDiskUse 现在它在抛出错误

TypeError: callback.apply is not a function

我已经找过了,但能找到解决办法…请帮助

const pictures = await Picture.aggregate([
      { $sort: { createdAt: -1 }},
      { $group: {
        _id: { $dateToString: { format: "%Y-%m-%d", date: "$createdAt" } },
        pictures: {
          $push: {
            _id: '$_id',
            image: '$image',
            time: { $dateToString: { format: "%H:%M:%S", date: "$createdAt" } }
          }
        }
      }},
      { $limit: 50 },
      { $project: {
        _id: false,
        createdAt: '$_id',
        pictures: '$pictures'
      }}
    ], { allowDiskUse: true })
