Impossible to delete Facebook Objects

Impossible to delete Facebook Objects

I'm trying to delete an object created by a story, but I'm getting the
following error :
(#100) Cannot delete object not created via the API
I used the FB.api in javascript to create a story with news.reads (works),
I can delete the story with the ID too. But the object created for the
story still exists, I can see it in the Graph API, but cannot delete it.
I want to fix this issue because if I try to create a story with the same
article link, if I change the content (the same link refers to a new
article), facebook will keep the old settings (title, image and
description don't change).
