Description

Seems Map schema type makes unnecessary conversion via __schemaType.applyGetters for updates query. I noted it when developing my custom types that based on MongooseBuffer, i just tried Map + UUID combination and got the same issue.

Steps to Reproduce

import mongoose from 'mongoose';
import { randomUUID } from 'node:crypto';

const Schema = new mongoose.Schema(
  {
    doc_map: {
      type: mongoose.Schema.Types.Map,
      of: mongoose.Schema.Types.UUID,
    },
  },
  { collection: 'users_test' },
);

const User = mongoose.model('TestUser', Schema);

async function test() {
  const user = new User({
    doc_map: new Map([
      ['role_1', randomUUID()],
      ['role_2', randomUUID()],
    ]),
  });

  await user.save();

  // all good here
  console.log(user.doc_map);

  // trying to update
  user.doc_map.set('role_1', randomUUID());

  await user.save();

  // got string in doc_map -> role_1
}

test().catch(console.error);

I couldn't get it to print via a console log but it does show as such in the db
