Free Gifts AJAX error – gift added but loading spinner never stops

Hello,
I have encountered an issue with the WoodMart Free Gifts feature on the cart page.
When a customer clicks “Add to cart” for one of the available free gifts, the gift is successfully added to the WooCommerce cart, but the AJAX loading spinner continues indefinitely and the cart interface is not updated.
After manually refreshing the page, the free gift appears correctly in the cart.
The issue is reproducible both for logged-in users and guests (tested in Incognito mode).
I checked the AJAX request in Chrome DevTools. The request completes successfully:
action: woodmart_add_gift_product
The server response is:
{“success”:true}
Immediately afterwards, the following JavaScript error occurs:
Uncaught TypeError: Cannot read properties of null (reading ‘invalidateResolutionForStore’)
at Object.success (freeGiftsTable.min.js)
So it appears that the gift is successfully added on the server side, but the JavaScript responsible for updating the cart interface fails after the successful AJAX response.
WoodMart and its bundled plugins are updated to the current versions.
Could you please check whether this is a bug or compatibility issue in the current Free Gifts implementation?
Thank you.
