Error confirming youtube API key

[emjas92]

I have set up everything according to the (incomplete) instructions, but I'm getting this after entering the auth code
Error confirming youtube API key
Error while trying to retrieve access token invalid_request

Does this project still work or is there a better one for downloading YT subs?

OK, so I see youtube-dl can do this itself.
I'm using the fork yt-dlp which has more features.

curl -s -L https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp -o ./yt-dlp
chmod a+rx ./yt-dlp
yt-dlp --batch-file channels.txt --download-archive archive.txt -S "res:720" --ignore-errors --windows-filenames -o "%(uploader)s/%(playlist)s/%(upload_date)s %(title)s.%(ext)s"
