@Robert-Harper Can you check if there is any required field on the container compoenent to be auhored before authroing the parsys?

@sufyan-ayub You can loop the multifield with the length of multifield and use name selector$("input[name='./<yourNameElement>']")with dynamic item values or use multifield wrapper selector and get the elements one by one and then select the checkboxes using seletors within the element for manupulat...

@Kavya6875 Can you check the permission- give rights to group everyone .Can you try and save as admin and see if that works?

@gmahesh No its just a component that has inner compoenents using a parsys, and when I add any component on that parsys, it throws this error.
