details property
Variables associated with this error that can be injected into a custom error template, or used to parameterize any other programatic actions.
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.
