Vercel error with youtube-dl-exec and Next js

I'm using Next js and youtube-dl-exec. I made endpoint /api/video/info with Next APIs in dir pages/api/video/info.js

info.js:

import youtubedl from 'youtube-dl-exec'

export default async function handler(req, res) {
  const { videoLink } = req.query
  if (!videoLink) {
    res.status(400).json({
      code: 400,
      message: 'Bad request: the video link is missing.',
    })
    return
  }
  try {
    const videoInfo = await youtubedl(videoLink, {
      dumpSingleJson: true,
      noWarnings: true,
      preferFreeFormats: true,
    })
    res.status(200).json({
      code: 200,
      data: {
        title: videoInfo.title,
        author: videoInfo.uploader,
        lengthSeconds: videoInfo.duration,
        viewCount: videoInfo.view_count,
        thumbnailUrl: videoInfo.thumbnail,
        description: videoInfo.description,
        formats: videoInfo.formats,
      },
    })
  } catch (error) {
    console.log(error)
    res.status(500).json({
      code: 500,
      message: "couldn't get video information",
      error,
    })
  }
}

The code works perfectly on my local machine on port 3000 and even after production with command npm run build and npm start it works fine on both environment (development or production) on my local machine but after deploying it to vercel when I call the endpoint, this error appears on vercel logs with status code 500:

What's the problem and how can I solve it?

I'm pretty sure youtube-dl-exec needs privileges to download and install yt-dlp

So it won't work on vercel

You will have to put this in a Docker container and deploy on a server of yours, or one serverless that supports docker

Let me know if you manage to do it as I'm interested
