We have purchased a Gift Card plugin v1.0.5. I am facing the below error while running the upgrade command on M2.2.0. Can guide how we can solve it?
Fatal error: Class 'Klarna\Core\Model\Checkout\Orderline\AbstractLine' not found in /home/fabhabit/public_html/devsite/app/code/Bss/GiftCard/Model/Checkout/Orderline/Giftcard.php on line 29
and coming above error while entering gift coupon code in the checkout page
Class Magento\Quote\Model\MaskedQuoteIdToQuoteIdInterface does not exist
Since Magento 2.2.x does not have the Klarna payment method as well as the class Magento\Quote\Model\MaskedQuoteIdToQuoteIdInterface does not exist so they cause the issues.
To fix this issue on m2.2.x, please follow our guide as below:
+ Step1: Remove the files that related to Klarna.
We have removed these files:
and edit this file app/code/Bss/GiftCard/etc/di.xml
+ Step 2: Fix the issue that class Magento\Quote\Model\MaskedQuoteIdToQuoteIdInterface does not exist since M2.2.0 does not this class.
We have changed the file app/code/Bss/GiftCard/Model/GiftCard.php
Please check and follow our guide and then replace the fixed files on your site.
