DiscordJS/MongoDB如何让bot正确更新值

const Discord = require('discord.js');
const MongoClient = require('mongodb').MongoClient;

const client = new Discord.Client();
client.login('YOUR_BOT_TOKEN');

client.on('ready', () => {
  MongoClient.connect('mongodb://localhost:27017', (err, client) => {
    if (err) {
      console.error('Failed to connect to MongoDB:', err);
      return;
    }
    console.log('Connected to MongoDB');
  });
});

client.on('message', (message) => {
  if (message.content.startsWith('!update')) {
    const userId = message.author.id;
    const newValue = 'New Value';

    const db = client.db('YOUR_DATABASE_NAME');
    const collection = db.collection('users');
    collection.updateOne({ id: userId }, { $set: { value: newValue } }, (err, result) => {
      if (err) {
        console.error('Failed to update value:', err);
        return;
      }
      console.log('Value updated successfully');
    });
  }
});
