What frappe function are you trying to use? If it can be done with jQuery or plain javascript do it that way.

return new Promise(function (resolve, reject) {

            try {

                frappe.call({

                    method: 'frappe.client.get_list',

                    args: {

                        doctype: opts.doctype,

                        fields: opts.fields,

                        filters: opts.filters,

                        order_by: opts.order_by,

                        limit_start: opts.limit_start,

                        limit_page_length: opts.limit_page_length,

                        parent: opts.parent

                    },

                    callback: resolve

                });

            } catch (e) { reject(e); }

        });

This frappe function I am trying to call from this path

/home/frappe/frappe-bench/apps/xyz/xyz/www/cart/js


can you try using above. It uses $.ajax instead of frappe.call. make a whitelisted custom function, allow_guest = True on the python side to return your list.
