39-91: LGTM! Robust error handling for sub-question processing.The changes effectively handle failed sub-questions and maintain consistency between async and sync execution paths. The filtering of failed results before synthesis prevents cascading errors.
Consider adding a warning log when all sub-questions fail, as this might indicate a systemic issue:
qa_pairs: List[SubQuestionAnswerPair] = list(filter(None, qa_pairs_all)) if qa_pairs: nodes = [self._construct_node(pair) for pair in qa_pairs] source_nodes = [ node for qa_pair in qa_pairs for node in qa_pair.sources ] response = self._response_synthesizer.synthesize( query=query_bundle, nodes=nodes, additional_source_nodes=source_nodes, ) else: + logger.warning( + f"All {len(sub_questions)} sub-questions failed for query: {query_bundle.query_str}" + ) response = Response(response=None, source_nodes=[])
101-103: Add return type hint for better code maintainability.The method's return type should be explicitly defined in the signature.
def _query_subq( self, sub_q: SubQuestion, color: Optional[str] = None - ) -> Optional[SubQuestionAnswerPair]: + ) -> Optional[SubQuestionAnswerPair]: # type: SubQuestionAnswerPair | None
128-132: Enhance error logging for better debugging.The current error logging could be more informative by including the exception traceback.
- logger.warning( + logger.warning( f"[{sub_q.tool_name}] Failed to run {sub_q.sub_question}: {exp}" - ) + exc_info=True + )

1-1: LGTM! Well-organized imports and proper logger setup.The addition of logging capabilities and necessary imports enhances the module's error handling capabilities.
Also applies to: 18-18
104-127: LGTM! Well-structured error handling with proper event tracking.The implementation effectively:
- Encapsulates sub-question processing logic
- Uses appropriate try-except pattern
- Maintains traceability through callback events
- Provides helpful debug information through verbose logging
