猫鼬在数组中添加子文档，给出错误_id：this.ownerDocument...model不是函数

如何解决猫鼬在数组中添加子文档，给出错误_id：this.ownerDocument...model不是函数

我有两种模式：

const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const _ = require("lodash");
const { regex } = require("../config/constants");
const { schemaErrors } = require("../config/errors");
const SiaSchema = require("./SiaModel");

const EmployeeSchema = new Schema(
    {
        first_name: {
            type: String,required: true,trim: true,},last_name: {
            type: String,mobile: {
            type: String,validate: {
                validator: function (v) {
                    return regex.uk.mobile.test(v);
                },message: schemaErrors.INVALID_MOBILE,sia: [SiaSchema],{ timestamps: { createdAt: "created_at",updatedAt: "updated_at" } }
);

EmployeeSchema.statics.addSia = async function (data) {
    let options = { new: true,upsert: true,runValidators: true };
    let sia = Object.assign({},data);
    delete sia._id;
    let orQuery = [];
    for (const attribute in sia) {
        orQuery.push({ [`sia.${attribute}`]: sia[attribute] });
    }
    let existing = await this.findOne({ $or: orQuery });
    if (existing) return Promise.resolve(existing);
    
    return this.findByIdAndUpdate(data._id,{ $push: { sia: sia } },options);
};

module.exports = EmployeeSchema; // I am not exporting mongoose model here because model creation for all schemas is being handled by another module

和

const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const _ = require("lodash");
const { regex } = require("../config/constants");
const { schemaErrors } = require("../config/errors");
const SiaSchema = new Schema(
    {
        sia_number: {
            type: String,validate: {
                validator: function (v) {
                    return regex.uk.sia.test(v);
                },message: schemaErrors.INVALID_SIA_NUMBER,issue_date: {
            type: Date,validate: {
                validator: function (v) {
                    return v instanceof Date && v.getTime() < Date.now();
                },message: schemaErrors.INVALID_ISSUE_DATE,expiration_date: {
            type: Date,validate: {
                validator: function (v) {
                    return v instanceof Date && v > this.issue_date;
                },message: schemaErrors.INVALID_EXPIRATION_DATE,updatedAt: "updated_at" } }
);

module.exports = SiaSchema; // I am not exporting mongoose model here because model creation for all schemas is being handled by another module

我创建了 Employee 。然后，我调用了另一个API，以使用 Employee Schema 中定义的 addSia 静态方法为该员工添加Sia，但这给了我以下错误：

"Validation failed: sia: Validation failed: _id: this.ownerDocument(...).model is not a function".

这是API的主体，数据作为data参数传递给addSia方法：

{
    "_id": "5f36cde0e4c4163838674219",// ID of the employee for whom I want to add sia
    "sia_number": "0000000000000000","issue_date": "2020-08-01","expiration_date": "2025-08-01"
}

如果我在addSia方法中从runValidators: true中删除了options，则该函数有效，但未应用验证。

在此方面的任何帮助，我将不胜感激。
