If I try to do a part refund for the order payed with credit card, I see this message: Processing refund failed..
In logs I see this messages:
2020-06-03T10:44:04+00:00 ERROR WC_Wirecard_Payment_Gateway::execute_refund:The transaction can not be refunded.
2020-06-03T10:44:04+00:00 DEBUG GET response: <html><head><title>500 Internal Server Error</title></head><body><h1>Internal Server Error</h1></body></html>We are testing with test credentials (https://api-test.wirecard.com). It should work, or?
