What problem does it solve?

This Skill establishes a consistent and robust approach to error handling in backend services, ensuring predictable error responses and effective logging.

Core Features & Use Cases

• Custom Exception Hierarchy: Define clear, domain-specific exceptions extending a base BusinessException.
• Global Exception Handling: Implement a centralized handler for all exceptions, mapping them to standardized error responses.
• Standardized Error Responses: Utilize a consistent DTO format for all API error messages.
• Logging Best Practices: Apply appropriate logging levels (INFO, WARN, ERROR) for different types of events.
• Use Case: When a user attempts to access a resource they don't have permission for, the backend throws a ForbiddenException, which is caught by the global handler and returns a 403 Forbidden status with a standardized error message.

Quick Start

Implement the Allra backend error handling standard by creating custom exceptions and a global exception handler.
