I'm having trouble with playFile()

I want download a audio file via ytdl-core and play it, but when i try to play it with connection.playFile() i get the following error:

This is the code i’ using:

async run(args: string[], msgObject: Discord.Message, client: Discord.Client): Promise<void> {  
    
    const url = args[0];
    var stream = ytdl(url);
    const streamOptions = { seek: 0, volume: 1 };
    try {
        
        
        await stream.pipe(fs.createWriteStream('tmp_buf_audio.mp3'))
        msgObject.delete();
        msgObject.member.voiceChannel.join()
            .then(connection =>{
                msgObject.reply("Succesfully joined")
                connection.playFile('./tmp_buf_audio', streamOptions)
                .on("end", () => {
                    connection.channel.leave();
                })
            })
            
    }
    catch {
        msgObject.channel.send("You have to  be in a Voicechannel to use this command");

        
    }

try this…

const client = require("discord.js");
const config = require("./config.json")
var stream = require("ytdl-core");
const streamOptions = { seek: 0, volume: 1 };

client.on("ready", async client => { console.log("connected.") }) client.on("message", async msgObject => {

    msgObject.delete();
    let voiceChannel = msgObject.guild.channels.find("id", message.author.guild.channel.id)
    msgObject.member.voiceChannel.join()
        .then(connection =>{
            msgObject.reply("Succesfully joined")
            connection.playFile('./tmp_buf_audio', streamOptions)
            .on("end", () => {
                voiceChannel.leave();
            })
        }).catch(error => {
   msgObject.reply("You have to be in a Voicechannel to use this command");

still getting the same error.

let voiceChannel = msgObject.guild.channels.find(“id”, message.author.guild.channel.id)
doesnt work because it returns a guild channel and not a voicechannel.
