message property
Message is the text that came with the command: what to say into the run for message, and the cancellation reason for stop. Up to 16 KiB. Empty on a bare pause or resume.
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
String? message;
