Description

Using the command youtube-dl -v https://www3.nhk.or.jp/nhkworld/en/ondemand/video/2019240/ results in the above traceback and an exit code of 1. The show for this URL is "Dining with chief".

However the command youtube-dl -v https://www3.nhk.or.jp/nhkworld/en/ondemand/video/2032106/ results in the expected video being downloaded without error. The show for this URL is "Japanology Plus".
