I tried to figure out why this wasn't working but no luck. My best guess was that there was a typo, but that's not it.

I think the best option would be to change the value to `youtube` so we don't promise anything we can't deliver. Open an issue and I'd also suggest asking on Stack Overflow what the deal is. It's likely it's a bug in the API. Google has a Developer Relations team which will monitor SO for questions tagged with 'youtube-api', so that's your best bet right now.
