youtube-api on JavaScript backend

After 2 weeks that I was using that API correctly and I have upload a few video on YouTube, today I receive this error when I try to get a new access token:

Error 400: invalid_scopeSome requested scopes were invalid. {invalid=[https://googleapis.com/auth/youtube.upload]}

Also with the old access token that was working yesterday, now I cannot proceed..

Now I can think that YouTube for some reason have blocked me or something like that because I haven't changed the code.. Anyone have experienced something like this? How I can proceed? At least I want to know if I was 'blocked' and for what reason.
