FastAPI Error Handling

About

This skill provides a comprehensive architecture for handling errors in FastAPI projects, ensuring consistency across all API endpoints. By implementing a hierarchy of custom exception classes, global middleware handlers, and Pydantic-driven response models, it allows developers to focus on business logic while maintaining a professional and predictable error interface. It also integrates structured JSON logging, which is essential for effective monitoring and debugging in production environments, making it an ideal foundation for building reliable and observable web services.

Key Features
