On attempting to install your module v2.2.7 on my site M2.4.3, we got the error as below:


PHP Fatal error:  Uncaught Error: Class 'Klarna\Core\Model\Checkout\Orderline\AbstractLine' not found in /home/xxx/xxx/xxxxx/public/app/code/Bss/OneStepCheckout/Model/Checkout/Orderlines/GiftWrapper.php:23

Please note that we remove Klarna's payment on our site.


The error happens due to the fact that our module was built to be compatible with Klarna payment. Hence, the error appears when this payment method is removed from the site.

To fix this error, please remove the file klarna.xml in app/code/Bss/OneStepCheckout/etc.

Remove the folder checkout in app/code/Bss/OneStepCheckout/Model.

And in the file app/code/OneStepCheckout/etc/di.xml, please remove the line:

<virtualType name="BssOscGiftWrapOrderlines" type="Bss\OneStepCheckout\Model\Checkout\Orderlines\GiftWrapper"/>
