message property
Message is why this attempt is not live: the failure, or the note that a newer deployment went live before this build finished. Empty while it is fine.
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.
