First thanks for creating and sharing with all.
As i am still using V12 i needed to backport so made some changes and now is working on V12.
Here are the changes:
// FROM GitHub - kid1194/frappe-better-attach-control: A small plugin for Frappe that adds the support of customizations to the attach control.
// Backported to V12
// Modifed by HeLKDYS: 18-09-2022
import {
isArray,
isDataObject,
deepCloneObject
} from ‘./utils/check.js’;
import {
to_images_list
} from ‘./utils/mime.js’;
//Helkyds change 18-09-2022
//frappe.ui.form.ControlData = class ControlData extends frappe.ui.form.ControlData{
frappe.ui.form.ControlAttach = class ControlAttach extends frappe.ui.form.ControlAttach {
