如果找不到角色创建新角色 |不和谐.js

Question

您好，我正在尝试为我的机器人制作颜色系统，但该命令会创建重复的角色。这是我的代码背后的基础知识。我希望它检查角色是否已经存在，然后不要再做。我该怎么做呢

const user = message.author;
        const member = message.guild.member(user);

       if (member.hasPermission('ADMINISTRATOR')) {
        message.guild.roles.create({
            data: {
                name: '#Red',
                color: 'ff0000',
                permissions: 0,
            }
        })
        message.channel.send('**Red Color Has Been Created!**')

if (message.guild.roles.cache.find(role => role.name == "#Red")) return false; // The role already exists.

message.guild.roles.create({ // Creating the role since it doesn't exist.
    data: {
        name: "#Red",
        color: "#ff0000",
        permissions: 0
    }
}).then(role => {
    message.channel.send(`Role \`${role.name}\` created!`);
});
