类型转换为String类型？"/>
MongoDB为什么在对象数组上将错误类型转换为String类型？
由于以下错误，我感到非常困惑，因为对我来说这几乎一样。
运行猫鼬种子，我有以下模型：
用户模型
const mongoose = require("mongoose")
const Schema = mongoose.Schema
const userSchema = new Schema({
firstName: String,
lastName: String,
title: String,
email: String,
password: String,
phone: String,
profilePicture: String,
profileDescription: String
}, {
timestamps: true
})
const User = mongoose.model("User", userSchema)
module.exports = User
CV型号
const mongoose = require("mongoose")
const Schema = mongoose.Schema
const cvSchema = new Schema({
name: String,
user: {
type: Schema.Types.ObjectId,
ref: 'User'
},
userInfo: {
firstName: String,
lastName: String,
title: String,
email: String,
password: String,
phone: String,
profilePicture: String,
profileDescription: [{}]
},
employment: [{
title: String,
employer: String,
start: String,
end: String,
city: String,
description: String,
}],
education: [{
degree: String,
school: String,
start: String,
end: String,
city: String,
description: String,
}],
skills: [{
skill: String,
level: Number,
}],
links: [{

}],
}, {

})
const CV = mongoose.model("CV", cvSchema)
module.exports = CV
描述模型
const mongoose = require("mongoose")
const Schema = mongoose.Schema
const descriptionSchema = new Schema({ description: [{}] })
const Description = mongoose.model("descriptionSchema", descriptionSchema)
module.exports = Description
和种子
require('dotenv').config()
const mongoose = require('mongoose')

const Description = require('../models/description.model')

.then(() => mongoose.connection.close()})
.catch(error => console.log(error))
您可以看到，user.profileDescription属性与描述模型是完全相同的模式（我是故意这样做的：我不打算使用描述模型）。
[运行种子时，描述模型运行完美：它创建了一个对象，其中存储了所有信息，但是对于CV模型，我得到以下强制转换错误：

我不知道为什么它指出了一个字符串转换错误，因为我正在使用user.profileDescription的对象
非常感谢您的帮助。
非常感谢。
回答如下：在简历模式中，您有profileDescription: [{}]，
所以profileDescription应该是对象数组，但是您传递了一个对象{ description: exampleDescription }
并且我看到您之前传递了一个字符串，但已评论
所以您需要直接传递数组exampleDescription
const users = [
{
firstName: "Example 1",
lastName: "Last Name 1",
title: "Student",
email: "[email protected]",
password: bcrypt.hashSync('pass1', salt),
phone: "123456789",
profilePicture: "https://qph.fs.quoracdn/main-qimg-134e3bf89fff27bf56bdbd04e7dbaedf.webp",
//profileDescription: "Experienced and dedicated Federal Government HR Manager with over ten years of experience, ensure HR systems support agencies in recruiting, hiring and retaining an excellent and diverse workforce.

profileDescription: exampleDescription, pass the array directly
},
{
firstName: "Demo 1",
lastName: "Demo 2",
title: "Yoga Instructor",
