ERROR: No card found (Card error)

#1

Description of issue:
There is meta for Twitter in HTML, and curl -v -A Twitterbot seems goes well. But the validator tells me ERROR: No card found (Card error) and there is no card indeed. There’s a robots.txt in the root and allow Twitter crawler.

The log of validator:

INFO:  Page fetched successfully
INFO:  7 metatags were found
ERROR: No card found (Card error)

I’m having a tough time loading the URL that you sent. This might be the cause of the issue here.
