Card Validation Issue: Invalid Card Type


I know it’s been asked here a lot, but I haven’t seen any real answers.

From what I can tell I have a valid card type, but I keep getting the error either way.


Relevant Meta Tags:

<meta name="twitter:card" content="summary">
<meta name="twitter:site" content="@crowdsourcelabs">
<meta name="twitter:description" content="Crowd Source Labs is a place to answer random questions about yourself and see how many others answer the same.  There is also the ability to look up correlations between the people who answer question 1 and question 2.">
<meta name="twitter:image:src" content="">
<meta name="twitter:title" content="How much do you sleep a night? I answered the same as 19% of all users.  See what you get!">

But for some reason it just doesn’t want to work.


Anything? I’ve spent several hours trying to fix this thing to no avail. It really feels like it should just work


Found out that the issue was that my content-type wasn’t set on the headers for the document. Seems like a bug, but I suppose it works now.


Saw that it wasn’t approved, so added your domain.

Let me know if it works for you!


Hey guys, We’re seeing the same issue.
I’ve double checked the meta tags and they validate if moved into the validator by hand.
There’s a content-type being declared on the page, and the domain shows as approved for other pages delivering the standard summary card, but the large image isn’t working.

Any ideas?
