versions property
Versions is how many revisions the prompt has, COUNTED in the store and uncapped — so it can exceed the 100 entries a list row or a detail response carries. Note the type: here versions is a number, while on a list row it is the list of version numbers.
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
int? versions;
