project property
Project narrows the repo to a sub-scope of the org. Omit it to use the caller's own X-Project-Id scope; it can never widen past the caller's org.
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? project;
