ERROR: Signature extraction failed: Traceback (most recent call last)

I was trying to download youtube playlist in mp3 format. When I tried below command, I was getting "ERROR: Signature extraction failed: Traceback (most recent call last)"

$youtube-dl -cit --extract-audio --audio-format mp3 https://www.youtube.com/playlist?list=PL4uUU2x5ZgR1JOlcY9SZB94MW6fBE8ovU

Pulled latest version and it is worked:

sudo wget https://yt-dl.org/latest/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+x /usr/local/bin/youtube-dl
hash -r
