批量删除如何工作？

我尝试使用bulkDelete让我的机器人删除其消息，但我收到此错误：

(node:5724) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Bad Request
(node:5724) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

这是我的代码：

const Discord = require('discord.js');
const bot = new Discord.Client();
const config = require("./config.json");

bot.on('ready', () =>{
    console.log('I am ready!');
});

//var cleanarr=[];

bot.on("message", message =>{
    if (message.author.bot) return;
var cleanarr=[];
        let command = message.content.split(" ")[0];
command = command.slice(config.prefix.length);

        let args = message.content.split(" ").slice(1);
if (message.content == 'lol'){
    message.channel.sendMessage('LUL');
    cleanarr.unshift(`${message.channel.lastMessageID}`);
    }
if (command == "clean") {
    message.channel.sendMessage('Cleaning...');
    message.channel.bulkDelete(cleanarr);
    var cleanarr = [];

批量删除需要什么？是消息id还是其他什么？

我不知道我这样做是否正确（显然我不是），因为我开始编码时对 javascript 或任何相关知识都是零。

最简单的删除方法x来自通道的消息是提供一个整数2 - 100作为参数<TextChannel>.bulkDelete https://discord.js.org/#/docs/main/stable/class/TextChannel?scrollTo=bulkDelete method.

Example:

message.channel.bulkDelete(100).then(() => {
  message.channel.send("Deleted 100 messages.").then(msg => msg.delete(3000));
});
