* fix: AI node connection validation in partial workflow updates (#357) Fix critical validation issue where n8n_update_partial_workflow incorrectly required 'main' connections for AI nodes that exclusively use AI-specific connection types (ai_languageModel, ai_memory, ai_embedding, ai_vectorStore, ai_tool). Problem: - Workflows containing AI nodes could not be updated via n8n_update_partial_workflow - Validation incorrectly expected ALL nodes to have 'main' connections - AI nodes only have AI-specific connection types, never 'main' Root Cause: - Zod schema in src/services/n8n-validation.ts defined 'main' as required field - Schema didn't support AI-specific connection types Fixed: - Made 'main' connection optional in Zod schema - Added support for all AI connection types: ai_tool, ai_languageModel, ai_memory, ai_embedding, ai_vectorStore - Created comprehensive test suite (13 tests) covering all AI connection scenarios - Updated documentation to clarify AI nodes don't require 'main' connections Testing: - All 13 new integration tests passing - Tested with actual workflow 019Vrw56aROeEzVj from issue #357 - Zero breaking changes (making required fields optional is always safe) Files Changed: - src/services/n8n-validation.ts - Fixed Zod schema - tests/integration/workflow-diff/ai-node-connection-validation.test.ts - New test suite - src/mcp/tool-docs/workflow_management/n8n-update-partial-workflow.ts - Updated docs - package.json - Version bump to 2.21.1 - CHANGELOG.md - Comprehensive release notes Closes #357 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> Conceived by Romuald Członkowski - www.aiadvisors.pl/en * fix: Add missing id parameter in test file and JSDoc comment Address code review feedback from PR #358: - Add 'id' field to all applyDiff calls in test file (fixes TypeScript errors) - Add JSDoc comment explaining why 'main' is optional in schema - Ensures TypeScript compilation succeeds Changes: - tests/integration/workflow-diff/ai-node-connection-validation.test.ts: Added id parameter to all 13 test cases - src/services/n8n-validation.ts: Added JSDoc explaining optional main connections Testing: - npm run typecheck: PASS ✅ - npm run build: PASS ✅ - All 13 tests: PASS ✅ 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>
