API開発

Implements robust, production-grade error handling patterns for n8n workflows to prevent silent failures and ensure self-healing capabilities.

This skill provides specialized guidance for building reliable n8n workflows, specifically focusing on webhook-triggered, scheduled, and production-bound processes. It enforces critical best practices such as wiring per-node error outputs, mapping HTTP status codes to specific causes, and implementing schema validation via IIFEs. By following these patterns, developers can transition from fragile workflows that halt silently to resilient, self-healing systems that provide structured error feedback and comprehensive monitoring via workflow-level error handlers.
