N8n Validation Expert

If you're working with n8n programmatically, you'll hit validation errors. This skill teaches you to interpret them and fix them in the typical 2-3 iteration loop (validate, think 23 seconds, fix, repeat). It breaks down the five validation profiles from minimal to strict, explains the difference between errors that block execution and warnings that don't, and walks through the six common error types like missing_required and invalid_reference. The patchNodeField section alone is worth it if you're doing partial workflow updates, since those operations are intentionally strict and fail loudly on ambiguous matches or missing strings.
