Save cover image from last.fm API to a png file with nodejs

Question

I'm trying to download the cover image from the trackSearch method of the last.fm API.

Here's what I've done :

lastfm.trackSearch({ q: song , limit : 1}, (err, data) => {
            if (err) console.error(err)
            else console.log(data)

            //console.log(data.result[0].images[0]);
            coverLink = data.result[0].images[0];

            request = http.get(coverLink, function(response) {
                response.pipe(file);

                // after download completed close filestream
                file.on("finish", () => {
                    file.close();
                    console.log("Download Completed");
                });
            });

        })

Result :

{
  meta: {
    query: { q: 'Halfway Home - TV On The Radio\r\n', limit: 1 },
    page: 1,
    perPage: 1,
    total: 163,
    totalPages: 163
  },
  result: [
    {
      type: 'track',
      name: 'Halfway Home',
      artistName: 'TV on the Radio',
      duration: undefined,
      listeners: 282831,
      images: [Array]
    }
  ]
}

Then it downloads a file, but the url isn't the right one. (https://lastfm.freetls.fastly.net/i/u/34s/2a96cbd8b46e442fc41c2b86b821562f.png)

What did I did wrong?
