如何查找所有没有角色的成员？discord.js v12

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 === '!findMembersWithoutRole') {
    const guild = message.guild;
    const members = await guild.members.fetch();
    
    const membersWithoutRole = members.filter((member) => member.roles.cache.size === 1);
    
    message.channel.send(`Members without roles: ${membersWithoutRole.map((member) => member.user.tag).join(', ')}`);
  }
});

client.login('YOUR_DISCORD_BOT_TOKEN');
