Steps to reproduce

Steps

const { id } = req.params;
const cookiePath = path.join(process.cwd(), "cookies.txt");
const cookieHeader = parseCookies(cookiePath);
const cachePath = path.join(process.cwd(), ".youtube-search-cache");

if (!existsSync(cachePath))
    await mkdir(cachePath, { recursive: true });

const userAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/139.0.0.0 Safari/537.36";

const yt = await Innertube.create({
    cookie: cookieHeader,
    cache: new UniversalCache(true, cachePath),
    user_agent: userAgent,
    retrieve_player: false,
    generate_session_locally: true,
    enable_session_cache: true,
    device_category: "desktop",
});

const info = await yt.getInfo(id); // ambil metadata
const audioFormat = info.streaming_data?.adaptive_formats?.find(f => f.mime_type.includes("audio/mp4"));
res.status(200).json({ success: true, audioFormat });
