Critical fixes: 1. Compute column: Add Chinese comma support in formula validation - Problem: Formula with Chinese comma failed validation - Fix: Add Chinese comma character to allowed_chars regex - Example: Support formulas like 'col1（kg）+ col2，col3' 2. Binning operation: Fix NaN serialization error - Problem: 'Out of range float values are not JSON compliant: nan' - Fix: Enhanced NaN/inf handling in binning endpoint - Added np.inf/-np.inf replacement before JSON serialization - Added manual JSON serialization with NaN->null conversion 3. Enhanced all operation endpoints for consistency - Updated conditional, dropna endpoints with same NaN/inf handling - Ensures all operations return JSON-compliant data Modified files: - extraction_service/operations/compute.py: Add Chinese comma to regex - extraction_service/main.py: Enhanced NaN handling in binning/conditional/dropna Status: Hotfix complete, ready for testing
