code property
Machine-readable error code. Stable across releases for the canonical codes (ambiguous_account, no_notes_provider, note_not_found). Absent for generic errors.
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? code;
