OptionalexecutionDurationMs?: numberOptionalexecutionTraceId?: stringBackend trace ID for the failed execution, when the error carries one.
OptionalqueryInfo?: QueryBuilderQueryInfoOptionaltimings?: TimingsRecordPhase timings collected up to the point of failure. Which laps are
missing is the useful signal: no
graph-manager.v1.engine-operation.server-call.success means the query
never reached the engine, so the failure is pre-flight rather than
in-flight.
Payload for query execution / plan / export failure events. Mirrors the shape of
LegendQueryTelemetryHelpercreator-failure payloads (errorName,errorMessage,httpStatus) so success/failure pairs can be joined on the same set of dimensions.
