往返文档在日期验证失败

Question

我定义了以下 Mongoose 架构：

const userSchema = new mongoose.Schema({
    //...
    createdOn: {
        type: Date,
        default: Date.now,
        required: true
    },
    //...
})
const UserModel = mongoose.model('User', userSchema)

但是当我尝试通过模型检索用户，然后验证用户时：

const user = await UserModel.findById('65dbf8b2a9a4828a79317571')
try {
    await user.validate()
} catch (err) {
    console.log(JSON.stringify(err))
}

我在

createdOn

属性上收到以下错误：

    "createdOn": {

  },

}

我在这里做错了什么？我该如何解决这个问题？

我上传到 MongoDB 的原始 JSON 末尾缺少

Z

。因此 Mongoose 无法识别该格式。
