What does the auto-sanitization system do?

It automatically fixes common operator structure issues, such as adding or removing the 'singleValue' property for binary and unary operators during workflow saves.

Will a 'Warning' stop my n8n workflow from running?

No, Warnings (like best_practice or performance) do not block execution, but they identify potential issues that should be addressed for a more stable production environment.

What is the recommended validation profile for n8n?

The 'runtime' profile is recommended for most pre-deployment use cases as it balances catching real errors with performance, covering required fields, types, and values.

How do I fix a 'missing_required' error in n8n?

Use the get_node_essentials tool to identify which field is missing, then update your node configuration with the appropriate value as specified in the error message.

Can this skill help with AI-generated n8n workflows?

Yes, it includes an 'ai-friendly' validation profile specifically designed to reduce false positives and be more tolerant of minor issues common in AI configurations.

生産性とワークフロー

Analyzes and resolves n8n workflow validation errors, providing iterative guidance for node configurations and structural issues.

The n8n Validation Expert skill is a specialized guide designed to help developers interpret and fix complex validation errors within n8n automations. It categorizes issues into Errors, Warnings, and Suggestions, guiding users through the necessary iterative cycles to reach a valid state. By offering support for different validation profiles—ranging from 'minimal' for quick edits to 'strict' for production-ready deployments—the skill ensures that workflows are not only functional but also follow best practices for performance and error handling. It also provides deep insights into n8n's auto-sanitization system for operator structures and workflow-level dependency auditing.
