UnhandledPromiseRejectionWarning: Error: No video id found

Question

Like the title says UnhandledPromiseRejectionWarning: Error: No video id found is what it says on the console after I sent a command: !join {link}. UnhandledPromiseRejectionWarning: Unhandled promise rejection shows up too.

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

function Play(connection, message) {
    var server = 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 JoinChannelCommand extends commando.Command {
    constructor(client)
    {
        super(client,{
            name: 'join',
            group: 'music',
            memberName: 'join',
            description: 'Join the voice channel'
        });
    }

    async run(message, args)
    {
        if(message.member.voiceChannel)
        {
            if(!message.guild.voiceConnection)
            {
                if(!servers[message.guild.id])
                {
                    servers[message.guild.id] = {queue: []}
                }
                message.member.voiceChannel.join()
                    .then(connection =>{
                        var server = servers[message.guild.id];
                        message.reply("Succesfully Joined!");
                        server.queue.push(args);
                        Play(connection, message);
                    })
            }
        }
        else
        {
            message.reply("You need to be in a voice channel to invite me Baka!")
        }
    }

}

module.exports = JoinChannelCommand;

An unhandled Promiserejection happens, when you promise gets rejected and you dont catch the error which it is producing. To get the error, which you want to handle, you may put a .catch statement after the .then statement. e.G:

            message.member.voiceChannel.join()
                .then(connection =>{
                    var server = servers[message.guild.id];
                    message.reply("Succesfully Joined!");
                    server.queue.push(args);
                    Play(connection, message);
                }).catch(e => { console.log(e) });

Maybe that will help you for your error handling.

Would be nice, if you vote my answer as solution, so that other users can see, what the solution is, without looking up the comments — Lukas Germerott, Jan 16 '19 at 11:59
