Pull request overview
This PR adds first-class Data Fabric (DF) error handling to uipath-platform by (1) classifying DF query-engine error codes into actionable categories and (2) integrating a DF-specific error payload extractor into the existing EnrichedException.error_info routing so callers can reliably extract message, error_code, and trace_id.
Changes:
- Introduces
DataFabricError+DataFabricErrorCategoryand a DF error-code classifier/mapping. - Adds a dedicated
datafabric_extractor and registers it in the error-extractor router. - Annotates
EntitiesServicequery methods with DF error-code metadata and adds tests for classification/extraction/routing.

Map DF query-engine error codes to actionable categories (retryable, bad_sql, infrastructure, data_issue) so callers can decide whether to retry, fix SQL, or surface an infra error. - Add datafabric_error_codes.py with code sets and classify_error_code - Add DataFabricError dataclass with from_enriched_exception / from_response_body - Add extract_datafabric extractor and wire it into the error router - Add attach_datafabric_error_mapping decorator on query_entity_records - Add comprehensive test suite for all new modules - Bump uipath-platform version to 0.1.90 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
