 * Error thrown when the indexer service API returns a failure envelope (see

 * with `status: 'failure'`. The numeric error code is exposed directly on
 * {@link BaseServerFailureError.errorCode} for comparison against {@link INDEXER_ERROR_CODES}.
 *
 * The v2 REST endpoints do not return a failure envelope — they use plain HTTP error responses
 * without an `error_code` field, so this error is only thrown for the v1 query routes.
