如何在nodejs中嵌套json对象

Question

我以MongoDB为数据库创建了一个NodeJS后端项目。我想创建一个文档，其中存储多个学生的详细信息。下面显示了我的控制器和模型文件。

Controller.js

const _user = new User({
  username: req.body.username,
  role: req.body.role,
  hash_password: hash_password,
  re_hash_password: req.body.re_hash_password,
  student:{
    member1: {
            fullName: req.body.student.member1.fullName,
            sliit_id: req.body.student.member1.sliit_id,
            phone: req.body.student.member1.phone,
            email: req.body.student.member1.email,
            specialization: req.body.student.member1.specialization,
    },
    member2: {
        fullName: req.body.student.member2.fullName,
        sliit_id: req.body.student.member2.sliit_id,
        phone: req.body.student.member2.phone,
        email: req.body.student.member2..email,
        specialization: req.body.student.member2.specialization,
    },  
  }

显示了我的Nodejs项目的控制器。在这里，我想将多个成员添加到我的MongoDB数据库中。

model.js

const demoStudentSchema = new mongoose.Schema({
    fullName: {
        type: String,
        required: true,
        trim: true,
        min: 3,
        max: 30
    },

    sliit_id: {
        type: String,
        required: true,
        trim: true,
        min: 3,
        max: 20
    },

    phone: {
        type: String,
        required: true
    },

    email: {
        type: String,
        required: true,
        trim: true,
        unique: true,
        lowercase: true
    },

    specialization: {
        type: String,
        enum: ['SE','CSNE','DS', 'ISE', 'CS']
    },

})
const userSchema = new mongoose.Schema({
    username: {
        type: String,
        required: true,
        trim: true,
        unique: true,
        index: true,
        min: 3,
        max: 20
    },

    role: {
        type: String,
        required:true,
        enum: ['student','supervisor','staff']
    },

    hash_password: {
        type: String,
        required: true,
    },

    re_hash_password: {
        type: String,
        required: true,
    },

    student: {
        member1: {
            demoStudentSchema
        },
        member2: {
            demoStudentSchema
        }
}
    
   

当我尝试使用Postman运行此代码时，会发生以下错误。

    }
}

我已经浏览了一些视频和文章，但无法找到任何解决方案。 您能帮我找出错误，并就解决此问题提出建议。
