Error Handling Guide

Common Error Types

• 🚫 404 Not Found: The requested resource doesn't exist.
• 🛑 500 Internal Server Error: A server-side issue occurred.
• ⚠️ 400 Bad Request: Invalid client request format.

Best Practices for Error Handling

1. 🔧 Use try-catch blocks to gracefully handle exceptions.
2. 📝 Log detailed errors for debugging, but avoid exposing sensitive info.
3. 🧠 Return user-friendly messages (e.g., "Page not found") instead of technical codes.
4. 🔄 Implement retries for transient errors like network issues.
5. 📌 Monitor and alert for critical errors using tools like error_monitoring_guide.

Debugging Tools

• 🛠️ Postman: Test APIs with pre-built request templates.
• 🧪 curl: Command-line tool for debugging HTTP requests.
• 📊 Sentinel: Monitor error rates and latency in real-time.
