There is a Python program. One of its functions is to retrieve data about YouTube videos using the youtube-dl library. The program is installed on the hosting Heroku . There are problems with this library on hosting.

From time to time, when working with youtube-dl , failures occur, due to which the command stops executing and cannot get information.

An error occurs when extracting information from a video:

This is a complete reproducible example. If you run it on your computer, then everything will be ok. Launch on Heroku – errors from the library immediately fly. The versions are the same, everything is identical.

from youtube_dl import YoutubeDL
YDL_OPTIONS = {'format': 'bestaudio', 'noplaylist': 'False', 'forcetitle': True, 'quiet': True}
def get_data (url):
  if not url.startswith ('https: //'):
    with YoutubeDL (YDL_OPTIONS) as ydl:
      info = ydl.extract_info (f'ytsearch: {url} ', download = False)
    url = 'https://youtu.be/' + info ['entries'] [0] ['id']
  with YoutubeDL (YDL_OPTIONS) as ydl:
    info = ydl.extract_info (url, download = False)
  title = info.get ('title')
  id_ = info.get ('id')
  URL = info ['formats'] [0] ['url']
  return title, id_, url
urls = ['https://www.youtube.com/watch?v=ueiqUx19vxw&ab_channel=CarMusic', 'https://youtu.be/9TnyItDcFdE', 'https://youtu.be/5QCaaAyz-yA' , 'https://youtu.be/0S13mP_pfEc', 'https://youtu.be/5QCaaAyz-yA', 'a fly is also a helicopter', 'del shannon run away', 'smeshariki', 'https: // www .youtube.com / watch? v = RTFyrZo8Dns & amp; ab_channel = detras']
for i in urls:
  title, id_, url = get_data (i)
  print (f'URL: {i} \ nTitle: {title} \ nID: {id _} \ nRaw: {url} \ n \ n ')

I get the same error from time to time:

WARNING: unable to extract player URL; please report this issue on https://yt-dl.org/bug. Make sure you are using the latest version; see https://yt-dl.org/update on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.

When I run it locally, on my computer – everything works, there are no questions.
This problem only occurs on hosting
