radchuk2012ParticipantGreetings!
I noticed for a long time that there is a floating failure appearing in the wc-status log:2023-12-27T09:43:43+00:00 CRITICAL Uncaught Error: Call to a member function get_tax_class() on null in /web/sites/zyabkin.ua/wp-content/plugins/woocommerce/includes/class-wc-cart-totals.php:232

I need your help!

radchuk2012ParticipantI looked at the nginx access log and built a chain simulating a failure:
1) This request was received after emptying the woodmart quick cart (woocommerce-mini-cart) by deleting the last item:
Answer from “action=woodmart_update_cart_item”
{“fragments”:{“div.widget_shopping_cart_content”:”<div class=\”widget_shopping_cart_content\”>\n<div class=\”shopping-cart-widget-body wd-scroll\”>\n\t<div class=\”wd-scroll-content\”>\n\n\t\t\n\t\t\t<div class=\”wd-empty-mini-cart\”>\n\t\t\t\t<p class=\”woocommerce-mini-cart__empty-message empty title\”>Немає товарів у кошику.<\/p>\n\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\tПовернутися до магазину\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n\n\t\t\n\t<\/div>\n<\/div>\n\n<div class=\”shopping-cart-widget-footer wd-cart-empty\”>\n\t\n\t<\/div>\n<\/div>”,”span.wd-cart-number_wd”:”\t\t<span class=\”wd-cart-number wd-tools-count\”>0 <span><\/span><\/span>\n\t\t”,”span.wd-cart-subtotal_wd”:”\t\t<span class=\”wd-cart-subtotal\”><span class=\”woocommerce-Price-amount amount\”><bdi>0,00 <span class=\”woocommerce-Price-currencySymbol\”>₴<\/span><\/bdi><\/span><\/span>\n\t\t”},”cart_hash”:””}2) Then a second GET is received with the same “item_id”, but “qty=1” and we get an error 500 which is reported in the logs (wc-status, nginx) – Thereby simulating crash for debugging purposes.
3) It seems that php does not check for a non-existent item_id with quantity – Probably here:

radchuk2012ParticipantApplied your patch – 524995
FIXED: “Update cart item” ajax action after cleaning the cart.
The 500 error no longer seems to cause.
Please let me know when access is no longer needed…
Probably the topic can be closed… it will take a long time to catch an error on the user’s side
Thanks for the quick fix!December 28, 2023 at 10:09 am #525091
Artem TemosKeymasterYes, this patch was created for this error. If it is fixed then let me know and I will close the topic.
Kind Regards

radchuk2012ParticipantGreetings!
I was no longer able to simulate a failure (500) with this request:I consider the problem closed, the topic can be closed.
Thank you!
