Returns the result of a succeeded async report operation, including report metadata (id, reportName, owner, type, createTime, updateTime, urlUI) when the operation was started against a saved report — the same shape as the sync GetReportResponse, instead of requiring a second call to GET /analytics/v1/reports/{id}/config for it. Returns 404 if the operationId does not exist, has expired, or belongs to a different tenant. Returns 425 Too Early if the operation has not yet reached a terminal state — poll the operation status endpoint, which returns its own Retry-After guidance, until it succeeds. Returns 422 if the operation terminated as failed or canceled. The poll status endpoint response does not include result data inline — this is the only endpoint that returns it.
