discord.js 中的冷却没有给出错误或工作

如何解决discord.js 中的冷却没有给出错误或工作

我正在尝试为我的处理程序添加冷却时间，这样我就不必在每个单独的命令中添加冷却时间。它没有发送任何错误或响应。

这是在消息事件处理程序中：

const args = message.content.slice(prefix.length).trim().split(/ +/g);
const cmd = args.shift().toLowerCase();
let command = client.commands.get(cmd);
//cooldowns
    const cooldowns = new Discord.Collection();
    if (!cooldowns.has(command.name)) {
        cooldowns.set(command.name,new Discord.Collection());
    }
    const now = Date.now();
    const timestamps = cooldowns.get(command.name);
    const cooldownAmount = (command.cooldown || 3) * 1000;

    if (timestamps.has(message.author.id)) {
        const expirationTime = timestamps.get(message.author.id) + cooldownAmount;
        if (now < expirationTime) {
            const timeLeft = (expirationTime - now) / 1000;
            return message.reply(`please wait ${timeLeft.toFixed(1)} more second(s) before reusing the \`${command.name}\` command.`);
        }
    }
    
    timestamps.set(message.author.id,now);
    setTimeout(() => timestamps.delete(message.author.id),cooldownAmount);
    //cooldowns

这是我在命令本身中的内容：

module.exports = {
    name: 'tag',aliases: ['tags','t'],cooldown: 5,category: 'fun',description: 'Create a custom command',usage: `tag create|delete|edit`,run: (client,message,args) => {

    return message.reply('test,command is not done yet this is to test the cooldown')
}}

我从这里得到了代码：https://discordjs.guide/command-handling/adding-features.html#cooldowns
