Get post-id after FB.ui() share

I need to get post-id after user clicks on the share button. My code so far:

$("#share").click(function(e) {
  e.preventDefault;
  FB.ui({
    method: 'share',
    href: 'developers.facebook.com',
  }, function(response){
    if(response && !response.error_code) {
      console.log(response); // => []
    } else {
      alert('err');
    }
  });
});

After content is successfully shared, the response I get is an empty array with no data. How can I get the post-id of share post?

Check out the docs for information about the response:

Only available if the user is logged into your app using Facebook and has granted publish_actions. If present, this is the ID of the published Open Graph story.

Meaning, you will only get the post-/object-id if the user is authorized with the publish_actions permission.
