Catch blocks written by AI return res.status(500).json({ error: error.message, stack: error.stack }), leaking internal file paths.
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.
