Library stopped working suddenly...

[Hitesh Kumar Saini]

Using following code:

let mode = 140
let video_url = new Promise(function (resolve, reject) {

    ytdl.getInfo(video_id, {}, (error, response) => {
        for (let index in response.formats) {
            if (response.formats[index].itag == mode) {
                resolve(response.formats[index].url);
                break;
            };
        };
    });
});

video_url
.then((url) => console.log(url));
