new api breaks my upload torrent script

[ljmerza]

I have a nodejs script that uploads torrents from urls. the latest api update on 4.2 seems to have broken this. here's the relevant code:

const formData = {
    paused: "true",
    autoTMM: "false",
    root_folder: "false",
    urls: torrent.downloadUrl,
    savepath: torrent.folderName,
    skip_checking: "false",
  };

  const response = await rp.post({ 
    json: true,
    url: `${config.seedbox.url}/api/v2/torrents/add`,
    jar: await getQbittorrentCookieJar(),
    headers: { "Content-Type": "multipart/form-data" },
    formData,
  });

  console.log(response);

the api comes back ok but the torrent isnt added. any changes i need to make here? v4.3.3
