addressChangeDeclined or lineItemChangeDeclined
When updating an order, the error message 'KlarnaPayment.errorMessages.lineItemChangeDeclined' or 'KlarnaPayment.errorMessages.addressChangeDeclined' appears.
- Due to Klarna's risk assessment, changes to order items and address are no longer possible once an amount has been captured via Klarna.
- To synchronise relevant changes to the order with Klarna, the Klarna plugin stores a hash of the address (
klarna_order_address_hash) and the order items (
klarna_order_cart_hash) in the custom fields of the order respectively. When the order is updated, the hashes are regenerated and compared with the existing ones. This is a simple way for the Klarna plugin to determine whether relevant data has been changed and to transfer this to Klarna. This can also result in an error message if the comparison is not possible due to missing hashes and no relevant data has been changed.
If you have not made any changes to the address or order items, please check the custom fields of the order via the database. If the mentioned hashes from the Klarna plugin are missing there, please contact plugin support.
When trying to complete an order, a pop-up appears with the message.
