Facebook Web data connector is not working on local server

I want to get new page(next fields of data) of a same Facebook page. I am using Facebook Web data connector. I have checked out the same code provided on github..But it is not working for me.. I am just trying to get all the data from pages belonging to particular user. I have used previous-reponse.paging.next to get next set of info but is not providing valid URI... instead it is showing "cursor" field containing two subfield "before" and "after"... Thank you in advance... Note : I am running the facebook WDC on local server..can say localhost:8888
