Node.js Mongoose不会更新数组中的属性值

以下是模式

export const publicTaskSchema = new Schema({
  task: { required: true, type: String },
  user: {   
    _user: { type: String, required: true },
    userName: { type: String, required: true },
   },
  likes: {
    users: [{ 
      _user: { type: String, required: true },
      userName: { type: String, required: true },
     }], 
   },
  comments: [{ 
    user: { 
      _user: { type: String, required: true },
      userName: { type: String, required: true },
     } 
   }],
});

export const publicTaskListSchema = new Schema({
  tasks: { required: true, type: [publicTaskSchema], default: null },
  totalTasks: { required: true, type: Number, default: 0 },
});

我所要做的就是更新嵌套数组中的属性.

为此，我try 将位置运算符与数组筛选器一起使用，以更新满足要求的所有任务.

        const updated = await PublicTaskList.updateMany<PublicTaskListType>(
          {},
          {
            $set: {
              "tasks.$[].comments.$[user].userName": req.user.profile?.userName,
            },
          },
          { arrayFilters: [{ "user.user._user": req.user._user }], new: true }
        ).exec();

我得到的只是这个回答
