更新嵌套文档参考

Question

我有一个名为MentorProfile的文档，其中引用了文档CommentFeed。我正在执行以下操作：

MentorProfile.findOneAndUpdate(
        {
            _id: req.body.profileId,
            'lessons._id': req.body.lessonId,
            'lessons.completedList.userData': { $ne: req.user._id }
        },
        {
            $push: {
                'lessons.$.completedList': {
                    name: req.user.name,
                    avatar: req.body.userAvatar,
                    userRecord: req.user._id
                }
            },
            $push: {
                'lessons.$.commentFeed.comments': {
                    user:{name:'name', avatar:'avatar', userRecord:'8u38u3jfj'}
                    text: 'test'
                }
            }
        },
        { new: true }
    )

我想向注释数组中推送新的注释，该数组嵌套如下：

  

    

MentorProfile> CommentFeed>评论

  

我所附的代码段无效，我确定我缺少明显的内容
