Line 1 states vatScenario "intra-eu-service", which is not one of the five scenarios this build knows: "domestic", "intra-eu-goods", "intra-eu-services", "export" and "small-business-exemption". Nothing was filled in from it, so the line has no VAT category.
ATW-VAT-SCENARIO-UNKNOWNDid you mean "intra-eu-services"? Set lines[0].vatScenario to one of the five, or remove it and state vatCategory (and vatRate) yourself.
