auth property
Auth is the caller's resolved credential for the connector, handed to the action verbatim. Its shape is whatever the connector's auth descriptor declares (a token string, an object), so it is opaque here.
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
Object? auth;
