Unable to retrieve Catagories via the API

I ran with "disableentitlement"

client.session.start(function (ks) {
      if (ks.code && ks.message) {
        //console.log('Error starting session', success, ks);
      } else {
        client.setKs(ks);
        var type = require('kaltura/KalturaVO');
        var filter = new type.KalturaMediaEntryFilter();
        var pager = new type.KalturaFilterPager();
        //var filter = new Filter();
        filter.referenceIdEqual = id;

        //console.log("Success: " + require('util').inspect(client, false, null));
        var res = client.media.listAction(mycb, filter, pager);
        //console.log("result is " + res);

      }
    }, "xxxxxxxxxxxxxxx",
    "a@xxxxxx.com",
    Kaltura.enums.KalturaSessionType.ADMIN,
    xxxxxxx,"", "disableentitlement");

Still nothing in the respective fields
