This is not my video. I used “Get Top Videos” api to store and use data in my program. Most of returned data had no problem. They always had thumbnail information so I could save them. But when ‘v171556209’ video was included in result, my program failed and I found out that it had no thumbnail info.
I think this occurs infrequently and data maybe is stored incorrectly. I want to know this can happen so I should handle this exception or this couldn’t have happened so I can always get thumbnail info.
