Description

The above error only occures with that specific file. YT-DL works well on other files of this site. Also the specific file could be played in browser.

Looks like whoever hacked on this extractor didn't follow coding conventions and decided to directly access the 'error' key instead of using dict.get. Should be an easy fix.

After fixing the coding mistake, this is my log:
