[1.2.8] How to fix 404 error when adding all products to cart from wishlist?

Issue: 

We have used Magento 2 Ajax add to cart version 1.2.8 on M2.4.3. But the extension does not work correctly with wishlist. 

When you are logged in and have added various items to the wishlist,  and then you decide to purchase them all at one time by clicking on the button: add all to cart, you get a 404 error.

Could you please check and solve the issue?

Solution:

The issue happens due to the module's bug with the current version 1.2.8.

To solve it, we have modified this file app/code/Bss/AjaxCart/view/frontend/web/js/ajax.js

Please overwrite this file or download the attachment file on your site.

If you have any issues, please feel free to contact us.

We'd like to help.
