如何自动更改不一致机器人的昵称。(Javascript)(Discord.js)

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

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

async function checkAndChangeNickname() {
    const guild = client.guilds.cache.get('YOUR_GUILD_ID');
    if (!guild) return console.error('Guild not found');

    const member = await guild.members.fetch(client.user.id);
    if (!member) return console.error('Bot member not found');

    const currentNickname = member.nickname || client.user.username;
    const desiredNickname = 'DesiredBotNickname'; // 设置你想要的昵称

    if (currentNickname !== desiredNickname) {
        try {
            await member.setNickname(desiredNickname);
            console.log(`Bot nickname changed to ${desiredNickname}`);
        } catch (error) {
            console.error(`Failed to change bot nickname: ${error}`);
        }
    }
}

client.login('YOUR_BOT_TOKEN');
