I found this at
developers.facebook.com/docs/sharing/reference/feed-dialog
The parameter post_id is in a 6 month deprecation window for use without publish_actionspermission. Beginning October 12, 2016, post_id requires your app to have publish_actions granted, and for the user to share to their timeline or a group.
This made the component unable to reward since april 12nd 2017
This will require the component to be rewritten, to add the publish_action to the permission of the app to be granted by users and user to choose the provacy of the app once for all.
