Need help to trigger workflow attached to service cataog by using cartjs api

[LydiaChester]

I am currently using sn_sc.CartJS() to submit a a catlog request using script include which is triggered by a business rule. The catalog item is submitting request successfully, req and ritm are getting created, but the flow attached to the service catalog is not getting triggered. There are a series of actions/ updates in the flow that needs to be triggered.

Any help is appreciated, Need to know if, by using cartjs to submit a catalog item, the flow will be triggered. currently it is not triggering the flow attached it to the catalog item. this is part of the script include example:

var cart = new sn_sc.CartJS();

            cart.empty();

            var item = {

                'sysparm_id': 'XXXXXXXXXXXXXXXXXXXXXXXXXXXX,

                'sysparm_quantity': '1',

                'variables': {

                    'group1': IncAsmntID.toString(),

                    'group12': groupID.toString()

                }

            };

            var cartDetails = cart.addToCart(item);

            //gs.info(JSON.stringify(cartDetails));

            //}

            //var request = cart.orderNow(item);

            var request = cart.submitOrder(item);
