message property
Message is CD's account of the phase — "successfully synced (all tasks run)" for a Succeeded operation, the reason it stopped for a Failed one.
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.
