Hello! I'm trying to override the default link thumbnail in my post, but for this particular one, the request succeeds but the thumb shows up blank on site.

Here is the POST request body for the request I'm making to /{page-id}/feed, as per the Custom Link Page Post Image section in https://developers.facebook.com/docs/graph-api/reference/v20.0/page/feed#publish

{
    "link": "https://www.huffpost.com/entry/weirdest-thing-seen-at-airport_l_66b3add9e4b05d0bc2808225",
    "name": "People Are Revealing The Weirdest Things They've Ever Seen At The Airport",
    "message": "What is it about the airport that brings out the bizarre in people?",
    "picture": "https://img.buzzfeed.com/pubhub-api-prod-us-east-1/assets/6cff236dbba745b2893760bc74d7b64f/test.png",
    "description": "What is it about the airport that brings out the bizarre in people?",
    "is_published": true
}

Is there something about this particular image/post that would cause the thumb to show up blank like this?
