Facebook Graph API: How could get full User ID who shares my Page post? – Facebook API

I’m using Graph API to get full User ID who shares my Page post. My Page post has 150 shares.

But when I use Url = Graph.facebook.com/{post_id}?sharedposts&access_token=’…’,
it only return a little userid and a cursor paging with ‘next’ url.

I continuously assign new url = ‘next’ but it return null data.

How could I get full user ID?

Thanks so much!!!
