Problem/Motivation

If the giftcard balance is modified manually during checkout process, an exception is thrown and the order cannot be completed.

Drupal\Core\Entity\EntityStorageException: Giftcard balance must not be negative in Drupal\Core\Entity\Sql\SqlContentEntityStorage->save() (line 815 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

Steps to reproduce

  • Create a giftcard manually
  • Add products to the cart, proceed to checkout
  • Redeem the giftcard from the giftcard pane
  • Add a giftcard transaction reducing the giftcard balance to 0
  • Click on the checkout submit button
  • Exception is thrown

Proposed resolution

Check the giftcard balance at checkout pane valitation step and prevent checkout completion if the giftcard balance has been modified.
