Typescript: InsertMany missing array overload with options

[t1bb4r]

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the bug has not already been reported

Mongoose version

6.12.0

Node.js version

16.20.1

MongoDB server version

4.4.x

Typescript version (if applicable)

4.9.5

Description

Using any options ({ordered: false}) with Model.InsertMany causes the return type to change. In the example I've forced the type parameter to cause a typescript error, but this also causes a problem without it. As we are inserting an array but there is no overload for this, it defaults to the 'single' insertion response type which is incorrect.

The issue is also present in mongoose 7.

#13904 seems closely related but not exactly, so I've decided to open a new issue.

Steps to Reproduce

export interface IUser {
  name: string;
}

export const usersSchema = new mongoose.Schema({
  name: {
    type: String,
  },
});

const Users = mongoose.model<IUser>('Users', usersSchema);

// insertOrderedSingle
Users.insertMany<{ name: string; }>({ name: 'Zildjian' });
// insertArray
Users.insertMany<{ name: string; }>([{ name: 'Zildjian' }]);
// insertArrayWithOptions
Users.insertMany<{ name: string; }>([{ name: 'Zildjian' }], {});

Expected Behavior

Normal options should not change the return type of InsertMany

import * as mongoose from 'mongoose';

interface IUser {
  name: string;
}

const usersSchema = new mongoose.Schema({
  name: {
    type: String,
  },
});

const Users = mongoose.model<IUser>('Users', usersSchema);

// insertOrderedSingle
Users.insertMany<{ name: string; }>({ name: 'Zildjian' });
// insertArray
Users.insertMany<{ name: string; }>([{ name: 'Zildjian' }]);
// insertArrayWithOptions
Users.insertMany<{ name: string; }>([{ name: 'Zildjian' }], {});
