Reactjs – number in terminal undefine or NaN

I have data in mongo. I fetch this data from mongo to screen. Then I want update data, by onClick (I select id) and send it to backend /api/folder
I can see object in terminal, BUT I cannot modify it.
Do you know why? Thanks

import db from "@/utils/db";
import Team from '@/modules/Team'


const handler = async (req, res) => {
  
  console.log(req.body)    // { id: '64501115948ae9070cdd5ba5' }

  await db.connect();


  const team = await Team.findById(req.query.id);

  console.log('team', team)
  console.log('name', team.name)
  console.log('game', team.game1)
  
  team.game1 += 1

  await team.save()

  await db.disconnect(); 
  res.status(200).json({ message: 'success '})
};

export default handler

terminal output / team.game1 === undefine
can you please tell me why is undefine and how to fix it?
thanks

    Finally, I got it, I change my mind and set new data in mongo database, BUT I DID NOT CHANGE MODULESCHEMA in pc. I saw data in database but could not change it because of module wasn't change! I will remember it!!!!

    Hey erza could you please replace your code-

    const handler = async (req, res) => {
  
  console.log(req.body)    // { id: '64501115948ae9070cdd5ba5' }

  await db.connect();


  const team = await Team.findById(req.query.id);

  console.log('team', team)
  console.log('name', team.name)
  console.log('game', team.game1)
  
  team.game1 += 1

  await team.save()

  await db.disconnect(); 
  res.status(200).json({ message: 'success '})
};

    with my code-

    const handler = async (req, res) => {
  
  console.log(req.body)

  await db.connect();


  const team = await Team.findById(req.query.id).lean().exec();

  console.log('team', team)
  console.log('name', team.name)
  console.log('game', team.game1)
  
  team.game1 += 1

  await Team.findByIdAndUpdate(req.query.id, { $set: team }).exec();

  await db.disconnect(); 
  res.status(200).json({ message: 'success '})
};

    if this doesn’t work just lemme know ii will help you more..
