Clicking Book Appointment, it gives error ,'The undefined value has no properties'.

In FSM on WO screen, there is UI action named Book Appointment, clicking it gives error as Your appointment cannot be scheduled. Reason: No valid application configuration found

I have the configuration set to scripted. everything is OOB. what is wrong

Open the "Book Appointment" UI action. In OOB UI action we have a function "openAppointmentBookingPopup()". In this function
Comment out this line - w.setPreference('sysparm_catalogId',"");

Modify the following lines:
w.setPreference('sysparm_openedFor',g_form.getValue('opened_by'));
w.setPreference('sysparm_location',g_form.getValue('location'));

Modified Function :

function openAppointmentBookingPopup() {
    GlideUI.get().clearOutputMessages();
    taskId = g_form.getUniqueValue() + "";
    if(taskId){
        taskTable = g_form.getTableName() + "";
        //w = new GlideDialogWindow("sn_apptmnt_booking_appointmentBooking_Popup")
        w = new GlideModal('sn_apptmnt_booking_appointmentBooking_Popup');
        w.setSize('modal-lg','1000');
        w.setTitle(getMessage('Select Appointment'));
        w.setPreference('sysparm_taskId',taskId);
        w.setPreference('sysparm_taskTable',taskTable);
        //w.setPreference('sysparm_catalogId',"cb0c5a30ff1131007a6dffffffffff30");
        //w.setPreference('sysparm_catalogId',"");
        w.setPreference('sysparm_openedFor',g_form.getValue('opened_by'));
        w.setPreference('sysparm_location',g_form.getValue('location'));
        w.render();  
    }else{
        GlideUI.get().addOutputMessage({'msg':getMessage('Please select one task to book appointment'),'type':'error'});
    }
}
