i was running WildFly 30 → Feature pack 2.2.0.Final →SmallRye GraphQL 2.5.0 included. -> graphql-java 20.2
i now upgraded to WildFly 33 →Feature pack 2.4.1.Final →SmallRye GraphQL 2.9.1 included -> graphql-java 22.1

now i get these errors when starting up:

Caused by: graphql.schema.validation.InvalidSchemaException: invalid schema:
object type 'BasicOrder' does not implement interface 'Order' because field 'orderId' is defined as 'String' type and not as 'String!' type
object type 'BasicOrder' does not implement interface 'Order' because field 'orderState' is defined as 'OrderState' type and not as 'OrderState!' type"}}

the classes are quite simple:

public interface Order {
	default String getOrderType() {
		return getClass().getSimpleName();
	}

	@NonNull
	String getOrderId();

	@NonNull
	OrderState getOrderState();
}

and

@Description("A generic order for basic orderInformation to return to the client")
@Getter
@Setter
@SuperBuilder
@NoArgsConstructor
public class BasicOrder implements Order {

	@NonNull
	@Setter(NONE) // not in GraphQL Input
	private String orderId;

	@NonNull
	@Setter(NONE) // not in GraphQL Input
	private OrderState orderState;
}

has aynone an idea why this may cause graphql trouble ? thanks
