javascript - Discord.js 机器人 "Unhanded Promised Rejection Type Error: Cannot Read Property 255890520990154752 of undefined"

Question

const commando = require('discord.js-commando');
const ytdl = require('ytdl-core');

function Play(connection, message) 
{
    var servers = servers[message.guild.id];
    server.dispatcher = connection.playStream(ytdl(`${server.queue[0]}`, {filter: "audioonly"}));
    server.queue.shift();
    server.dispatcher.on("end",  function(){
        if(server.queue[0])
        {
            Play(connection, message);
        }else
        {
            connection.disconnect();
        }
    });

}

class PlayCommand extends commando.Command
{
    constructor(client)
    {
        super(client,{
            name: 'play',
            group: 'music',
            memberName: 'play',
            description: 'Plays music!'
        });
    }

    async run(message, args)
    {
        if (!permissions.has('CONNECT') || !permissions.has('SPEAK')) {
            return message.channel.send('I need the permissions to join and speak in your voice channel!');
        }

        if(message.member.voiceChannel)
        {
            if(!message.guild.voiceConnection)
            {
                if(!servers[message.guild.id])
                {
                    var server = servers[message.guild.id];
                    servers[message.guild.id] = {queue: []}
                }
                message.member.voiceChannel.join()
                    .then(connection => {
                        var servers = servers[message.guild.id];
                        message.reply("Sucessfully Joined Channel!");

                        let validate = await ytdl.validateURL(args);
                        if(!validate) return message.channel.send('Sorry, Please input a **valid** url.');

                        server.queue.push(args);
                        Play(connection, message);
                    })
            }
        }
        else{
            message.reply("You must be in a voice channel to use that command! ")
        }

        console.log(message.author.username + ' Used a ' + 'music' + ' command \n');
    }
}

module.exports = PlayCommand;

这是机器人上“播放”命令的代码。机器人的工作是使用 ytdl 库播放音乐。

我不确定问题出在哪里；起初，我认为可能没有找到库或安装错误，所以我重新安装了所有库(ytdl-core、discord.js、discord.js-commando...)

还是什么都没有!

我对 Javascript 不太熟悉，尤其是错误代码，因此非常感谢任何帮助或指导正确方向来帮助解决问题!

这是我在这里提出的第一个问题，因此对于任何不一致之处我深表歉意。

完整的错误代码:

(node:18216) [DEP0018] 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.

看起来您的servers变量可能从未初始化过。确保它确实包含正确的公会。
