How we can use Js Mixins for order scripts.js

Question

I want to override switchPaymentMethod from module-sales/view/adminhtml/web/order/create/scripts.js for that I use mixins:

app/code/Vendor/Module/view/adminhtml/requirejs-config.js

var config = {
 config: {
 mixins: {
 'Magento_Sales/order/create/scripts': {
 'Vendor_Module/order/create/scripts-mixin': true
 }
 }
 }
};

app/code/Vendor/Module/view/adminhtml/web/order/create/scripts-mixin.js

define(function () {
 'use strict';
 var mixin = {
 switchPaymentMethod: function(method){
 console.log('funcion called');
 //Main Code
 },
 };
 return function (target) {
 return target.extend(mixin);
 };
});

I got this error in console: Cannot read property 'extend' of undefined

I also tried with override AdminOrder.prototype = { }

Any help would be appreciated...!

• Mahi M: @Patel Did you solve this?
• Prince Patel: @ManoM Yes, After deep into the code found that you can't use mixins in this case. I will provide my solution soon here.

you must change config to :

var config = {
 config: {
 mixins: {
 'Vendor_Module/order/create/scripts-mixin' : {
 'Magento_Sales/order/create/scripts': true
 }
 }
 }
};
