Unable to retrieve single page

[dmj2144]

Most likely this is something I am doing wrong but, all I want to do is retrieve a set of fields for a particular page. I have written the following:

var appId = foo;
var appSecret = bar;
var token = baz;

var Facebook = require('facebook-node-sdk');
var facebook = new Facebook( { appID: appId, secret : appSecret });
facebook.setAccessToken(token);

facebook.api('/15254154654', 'GET', {"fields" : "id,name" }, function(response) { console.log(response); });

Every single time this returns a 'null' response. I cannot for the life of me figure out the reason. I have run the query inside the Explorer and it works fine but, this fails.

Any ideas ?
