error property
Error is why the run failed, clamped to 64 KiB. It is CLAMPED rather than refused — a truncated reason is worth more than a rejected report, because a rejected report leaves the durable workflow waiting forever.
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.
