updatedAt property
UpdatedAt is the last time any field above was written, same format. It moves on an update to the DEFINITION and never on a run, so a busy agent nobody has edited keeps an old 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.
Implementation
String? updatedAt;
