I'm getting the same result

Hi, thanks for reporting! It seems that YouTube has made some changes which caused the translationLanguages key to sometimes be missing from the captions json. I just published v0.6.2, which initializes translation_languages with an empty list in case that happens. So upgrading to v0.6.2 should fix this error!
