===============================================

Please fix it if you can. I'm using the latest 2019.04.30 version.

I figured out the problem. There's no subtitle/transcript for that particular video. So the download stops and that error appears.

This error should be fixed.. so that even if there's no subtitle/transcript then downloading should continue, just skip the download of subtitle/transcript it it's not available.

Nevermind, I figured out the solution. Just add " -ciw" (without quotes) at the end of the line.

It's good to use a combination of -ciw when downloading playlists.

-i, --ignore-errors Continue on download errors, for example to skip
unavailable videos in a playlist
-w, --no-overwrites Do not overwrite files
-c, --continue Force resume of partially downloaded files.
By default, youtube-dl will resume downloads if possible.
