No Swallowed Catch Blocks (Empty catch (e) {})
When async code throws, AI agents wrap it in try { ... } catch (e) {} with no logging or error handling, making production bugs impossible to diagnose.
Review my codebase for "No Swallowed Catch Blocks (Empty catch (e) {})" (ERR-001).
Issue: When async code throws, AI agents wrap it in try { ... } catch (e) {} with no logging or error handling, making production bugs impossible to diagnose.
Remediation required: Log caught errors to an observability tool and return structured error responses to the caller.
Please:
1. Locate any occurrences of this issue across my repository.
2. Refactor the code to follow production standards without breaking existing functionality.
3. Provide a clear command or step to test and verify the fix.Why AI Assistants Write This Bug
When async code throws, AI agents wrap it in try { ... } catch (e) {} with no logging or error handling, making production bugs impossible to diagnose.
AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.
