## Known Issues & Solutions

### Issue 1: Pydantic v2 Incompatibility
**Problem**: PyObjectId validator using v1 pattern caused TypeError
**Solution**: Simplified to use `Optional[str]` for id fields, convert ObjectId in service layer
**Status**: ✅ Resolved

### Issue 2: Environment Variable Override
**Problem**: System env vars overriding .env file
**Solution**: Start server with explicit MONGODB_URL environment variable
**Status**: ✅ Resolved

### Issue 3: Port Conflict
**Problem**: Port 8100 used by pipeline_monitor
**Solution**: Changed to port 8101
**Status**: ✅ Resolved
