httpStatus property
HTTPStatus is what the subscriber answered. ZERO means it never answered — a refused connection, a DNS failure or a timeout — which is why a zero here is not a 200.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? httpStatus;
