ytdl() error: The "url" argument must be of type string. Received type undefined

Question

I'm experiencing an issue with both ytdl( ) and downloadFromInfo( ) functions.

Error:

TypeError_ [ERR_INVALID_ARG_TYPE]: The "url" argument must be of type string. Received type undefined

at validateString (internal/validators.js:107:11)
at Url.parse (url.js:155:3)
at Object.urlParse [as parse] (url.js:150:13)

at processTicksAndRejections (internal/process/task_queues.js:75:11)

In the case of ytdl( ) I checked if my input was incorrect, but it wasn't. I believe there may be a problem when ytdl-core tries to read the object from the getInfo( ) function.

With some videos it does work, but those cases are rare.

This is the code I use, I have checked all my variables, including songInfo and they all seem to be correct, the error only appears when I run ytdl( ) or downloadFromInfo( ).

async function playSong(channela, message){
var songInfo;
var songTitle;
let connection;
let dispatcher;

if(typeof servers[message.guild.id].queue[0] === 'undefined' || !servers[message.guild.id].queue[0] || typeof servers[message.guild.id].queue[0] !== 'string'){
    servers[message.guild.id].queue.shift();
    if(!servers[message.guild.id].queue[0]){
        connection.disconnect();
        message.member.voice.channel.leave();
    }
}
try{
    songInfo = await ytdl.getInfo(servers[message.guild.id].queue[0]);
    songTitle = songInfo.title;
    connection = await channela.join();
    let stream = await ytdl.downloadFromInfo(songInfo, {filter: 'audioonly', quality: 'highestaudio', highWaterMark: 1<<25});
    dispatcher = await connection.play(stream, {highWaterMark: 1});
}catch(error){
    console.error('Could not play the video:' + error);
    message.channel.send('**Please, try again.**');
} 

Thank you for your time.

For me the trick was to globally uninstall the package and install it back.

> npm uninstall -g ytdl-core --save
> npm install ytdl-core
