- Add nil checks and proper error handling for utils.item_to_string calls - Prevent runtime errors when item_to_string returns nil values - Add warning logs when parsing fails to help with debugging - Skip processing invalid decisions gracefully instead of crashing - Fix issues in both stream.lua and live.lua files This resolves the runtime error: "attempt to concatenate local 'ip_type' (a nil value)" The code now handles cases where IP addresses or decision values cannot be parsed and logs appropriate warnings while continuing execution.
- Replace goto statements with proper if-else blocks for better readability - Refactor utils.item_to_string scope checking to use elseif/else pattern - Add explicit handling for unsupported scopes in item_to_string - Make return value assignments more explicit with _ for ignored values - Improve code maintainability and readability
- Eliminate duplicate calls to utils.item_to_string in deletion processing - Use single parsing result for both deletion and cache operations - Improve performance by reducing redundant IP parsing - Maintain same functionality with better efficiency
- Use single parsing result for both deletion and cache operations - Improve performance by eliminating duplicate function calls - Maintain proper captcha handling independent of key parsing - Preserve all original functionality with better efficiency
- Use single utils.item_to_string call for both deletion and cache operations - Maintain proper captcha handling independent of key parsing - Improve performance while preserving all original functionality - Ensure correct logic flow for decision processing

fix #128
This resolves the runtime error:
"attempt to concatenate local 'ip_type' (a nil value)"
The code now handles cases where IP addresses or decision values cannot be parsed and logs appropriate warnings while continuing execution.
