Fixed critical bug where AI Agent validator never executed, missing 179 configuration errors (30% of all telemetry-identified failures). The Bug: - Switch case checked for '@n8n/n8n-nodes-langchain.agent' (full package format) - But nodeType was normalized to 'nodes-langchain.agent' before reaching switch - Result: AI Agent validator never matched, never executed The Fix: - Changed case to 'nodes-langchain.agent' to match normalized format - Now correctly catches prompt configuration, maxIterations, error handling issues Files Changed: - src/services/enhanced-config-validator.ts:322 - Fixed nodeType format - tests/unit/services/enhanced-config-validator.test.ts - Added validateAIAgent to mock and verification test - CHANGELOG.md - Added bug fix section to 2.22.13 (not separate version) Testing: - npm test -- tests/unit/services/enhanced-config-validator.test.ts - ✓ All 51 tests pass including new AI Agent validation test Discovery: Discovered by n8n-mcp-tester agent during post-deployment verification of 2.22.13 improvements. The agent attempted to validate an AI Agent node configuration and discovered the validator was never being called. Impact: - Without fix: 179 AI Agent configuration errors (30%) go undetected - With fix: All AI Agent validation rules now execute correctly Version: 2.22.13 (kept under same version as original implementation) Concieved by Romuald Członkowski - www.aiadvisors.pl/en
