如何在discord.js v12中从guild.fetch获取ID？

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}`);
});

client.on('message', async (message) => {
  if (message.content === '!getGuildID') {
    try {
      const guild = await client.guilds.fetch(message.guild.id);
      const guildID = guild.id;
      message.channel.send(`The ID of this guild is: ${guildID}`);
    } catch (error) {
      console.error('Error fetching guild:', error);
    }
  }
});

client.login('YOUR_DISCORD_BOT_TOKEN');

npm install discord.js@12
