Error Message on Klarna Checkout page

Hi,

My webstore Klarna Check out page showing the error code when the customer tried to proceed the payment. Customer didn’t press the button to proceed the payment, but he still received the notification from Klarna apps and his money is reserved for the product. However, in our woocommerce system, we can’t see his order.

/// ! {“error_code”:”READ_ONLY_ORDER”,”error_messages”??”Resource is read-only”],”correlation_id”:”bc1017a4-8786-4efb-97a9-79815eec7947″,”service_version”:”1.0.20200320090732″} Resource is read-only///

And when we chatted with Klarna about this error, they replied that “the response signals from Woocommerce doesn’t go ahead. It means the order is in Klarna system but the signals fail to be recorded in the Woocommerce system.”

My website using the below plug in:
Woocommerce 4.0.1
Klarna Checkout 2.0.8
Klarna Order Management 1.5.1

Please advise. Thank you very much.

Best Regards,
Ivy
