discord.js / ytdl-core play command

this is my second question today. I'm using discord.js v13. Earlier I looked into finding out how to make audio play from the bot, and now I am attempting to make a queue work for my discord.js bot. My problem is getting the queue defined from index.js correctly. I will provide the error log along with my code.

Any help is appreciated because I'm really not smart and I'm still trying to learn how all this stuff works, especially with discord.js v13

In
video_player(message.guild, queue_constructor.songs[0]);
You only put two parameters and as you said in the comments, you only had to change it to this to fix your problem
video_player(message.guild, queue_constructor.songs[0], queue, audioPlayer)

undefined song when I run the play command

I'm trying to build a music discord bot with yt-search but it gives me undefined whenever I play the song and it joins the voice channel without playing the song. I'm trying to use yt-search to find the video I want or only the URL then pass it to ytdl to run it with the URL given from yt-search but I think I'm wrong in some points. I don't know where, could you please fix my code ?
Image to show the problem:

There are two errors. I'm not sure what you think args[1,2] is but it's the same as args[2] which is the third item of the args array. By reading your code, I think you want to use a string here, the search term. By removing the first item (the command) from the args array and joining the rest of them, you will receive a string you can use as keywords. Check out the example below:
const message = { content: '!play some music I want'}
const args = message.content.split(' ')
console.log({ args })
// => ["!play", "some", "music", "I", "want"]
console.log({ 'args[1, 2]': args[1, 2] })
// => "music"
console.log({ 'search': args.slice(1).join(' ') })
// => "some music I want"
The other error is that await yts(query) returns an array of results and when you define the video variable you use r.videos.slice(0, 1). The .slice() method returns a new array with the first item of r.videos.
As the video variable is an array, video.url is undefined. You could fix it by using the first item instead as it will have a url property. You should also check if there are any search results.
Check out the updated code below:
async function execute(message, serverQueue) {
const args = message.content.split(' ');
const voiceChannel = message.member.voice.channel;
if (!voiceChannel)
return message.channel.send(
'You need to be in a voice channel to play music!',
);
const permissions = voiceChannel.permissionsFor(message.client.user);
if (!permissions.has('CONNECT') || !permissions.has('SPEAK')) {
return message.channel.send(
'I need the permissions to join and speak in your voice channel!',
);
}
const query = args.slice(1).join(' ');
const results = await yts(query);
if (!results.videos.length)
return message.channel.send(`No results for \`${query}\``);
const firstVideo = results.videos[0];
const songInfo = await ytdl.getInfo(firstVideo.url);
const song = {
title: songInfo.videoDetails.title,
url: songInfo.videoDetails.video_url,
};
console.log(song);
if (!serverQueue) {

Someone can help me plese?

If its supposed to return an object, put parentheses around it, like this:
// From
module.exports.run = async (bot, message, args) => {
...
};
// To
module.exports.run = async (bot, message, args) => ({
...
});

(node:656) UnhandledPromiseRejectionWarning: ReferenceError: prefix is not defined error

I'm currently trying to get my Discord bot to play music in the Discord, I have all this code typed up and it's coming up with this error:
