spec property
Spec is API documentation — an OpenAPI document, or prose describing the endpoints — that the generator turns into Source. The generated source is returned in the response, so a caller can read what will run before it runs.
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.
