action property
Action is the verb that was performed. It is the event's name, not the HTTP method — a request-sourced record carries both, and the pair is what makes a row readable ("grant.create" at POST /v1/admin/grants).
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? action;
