I created a custom story for Open Graph (Spot a Special). I would like to be able to post this on a user’s wall with a card attached, so I configured it as such:

I set the "Hilighted Points" attribute to "special.location" and defined the location attribute in my "special" object:

Then I try to publish this story (using Graph Explorer) with https://graph.facebook.com/me/objects/ishoppapp:specialaccess_token=ACCESS_TOKEN&method=POST&object=MY_OBJECT
MY_OBJECT :
{
"app_id":277886232371318,
"type":"ishoppapp:special",
"url":"http://ishopp.co.za/ogp.html",
"title":"Sample Special",
"description":"This is a huge description.",
"data": {
"discount": 20,
"location": {
"latitude": -33,
"longitude": 18
}
}
}
And the og tags at http://ishopp.co.za/ogp.html :
<meta property="fb:app_id" content="277886232371318">
<meta property="og:title" content="Sample Spec">
<meta property="og:image" content="http://placehold.it/250x250">
<meta property="og:url" content="http://ishopp.co.za/ogp.html">
<meta property="og:type" content="ishoppapp:special">
<meta property="ishoppapp:discount" content="20" />
<meta property="ishoppapp:location:latitude" content="-33.00" />
However, when I publish this, all I get is: No card ...

I noticed that he says “sent” instead of “spotted”. When using, /me/ishoppapp:spot/?special=http://ishopp.co.za/ogp.htmlI get:

But still there is no card ...
What is the fix for this?
