Preconditions (*)

Magento 2.4

Steps to reproduce (*)

On Magneto 2.4.x on group product when trying to add it to the cart I get this error:

Issue relates to #24955

Issue 24955 says it relates to stock level but this doesn't seem to be true. It seems to be caused if any of these values is 0:

Issue is caused by this code in vendor/magento/module-grouped-product/Model/Product/Type/Grouped.php :

Expected result (*)

It should add the item to the basket without error.

Actual result (*)

Item is not added to basket.
