Card not showing up


hi, I am trying to tweet with a card of summary_large_image.
I had put theses meta contents in html of page i am sharing.

meta name="twitter:card" content="summary_large_image"
meta name="twitter:site" content="@promon"
meta name="twitter:creator" content="@sunken_Joy"
meta name="twitter:title" content="kjasbdkjasd"
meta name="twitter:description" content="kagskfaskjsfgjkasf"
meta name="twitter:image" content="{{product.fb_share_image.url}}"
meta name="twitter:domain" content=""

I am using this javascript to pop-up the twitter modal.

    		text: '#HelloWorld',

{{product.fb_image_share.url}} gives me links to image which is dynamically assigned on the basis of product.
But image is not showing up, i am able to post the tweet though.
the card-validator says “Unable to render Card preview”.I have been banging my head over 2 days now. Please suggest me a solution.


Can you link us to the page where the meta tags are included?


You need to use a proper DNS name in order for the cards crawler to find your content.

Can you share a fully-qualified DNS URL where we can take a look at your site with cards markup?


thanks. I got the image showing up once i tried it on production.
