UnknownScreenName with twitter:creator


Cards that used to work are now broken if they contain a twitter:creator attribute.
For example, for http://yoast.com/twitter-cards/, the preview tool returns:

Fetcher response code: OK
UnknownScreenName: twitter:creator; value=@yoast

Update: seems to have been a temporary Twitter problem, works now without code changes.


I’m getting the same error for @ajjoshi when testing http://www.ajjoshi.com/pic/1555

Any idea how this can be fixed?


Is this still happening? It might have been a transient bug.


It seems to have been a temporary bug indeed – I don’t experience the issue anymore.


I can confirm it was a temporary bug, please advise if you see it again (I think it squashed but keeping our eyes open).
