Is it possible to create a Twitter card from a data URI?


I am trying to create a Twitter Card using data-URIs. I started with the sample code for summary cards and urlencoded a page:


However, the Card validator did not accept that, since it needed a http-url. So, I tried using a url-shortener: but this did not work either, only giving me the following error:

Fetching the page failed due to an internal error, debugId: 3529608922962-768183

Am I correct in assuming that this approach wont work? Is it a bug or a feature request? :slight_smile:
