From fe1e3640afc807a6873ae9d7775f6076f6c6d482 Mon Sep 17 00:00:00 2001 From: czlonkowski <56956555+czlonkowski@users.noreply.github.com> Date: Thu, 2 Oct 2025 15:58:37 +0200 Subject: [PATCH] fix: correct Issue #248 - remove settings entirely from workflow updates MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previous fix attempted to whitelist settings properties, but research revealed that the n8n API update endpoint does NOT support updating settings at all. Root Cause: - n8n API rejects ANY settings properties in update requests - Properties like callerPolicy and executionOrder cannot be updated via API - See: https://community.n8n.io/t/api-workflow-update-endpoint-doesnt-support-setting-callerpolicy/161916 Solution: - Remove settings object entirely from update payloads - n8n API preserves existing settings when omitted from updates - Prevents "settings must NOT have additional properties" errors Changes: - src/services/n8n-validation.ts: Replace whitelist filtering with complete removal - tests/unit/services/n8n-validation.test.ts: Update tests to verify settings removal Testing: - All 72 unit tests passing (100% coverage) - Verified with n8n-mcp-tester on cloud workflow (n8n.estyl.team) Impact: - Workflow updates (name, nodes, connections) work correctly - Settings are preserved (not lost, just not updated) - Resolves all "settings must NOT have additional properties" errors 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/services/n8n-validation.ts | 31 +++---- tests/unit/services/n8n-validation.test.ts | 99 ++++++---------------- 2 files changed, 36 insertions(+), 94 deletions(-) diff --git a/src/services/n8n-validation.ts b/src/services/n8n-validation.ts index 9448234..120f80e 100644 --- a/src/services/n8n-validation.ts +++ b/src/services/n8n-validation.ts @@ -133,28 +133,17 @@ export function cleanWorkflowForUpdate(workflow: Workflow): Partial { ...cleanedWorkflow } = workflow as any; - // Filter settings to only include valid properties (Issue #248 fix) - // Prevents "settings must NOT have additional properties" API errors + // CRITICAL FIX for Issue #248: + // The n8n API update endpoint has a strict schema that REJECTS settings updates. + // Properties like callerPolicy and executionOrder cannot be updated via the API + // (see: https://community.n8n.io/t/api-workflow-update-endpoint-doesnt-support-setting-callerpolicy/161916) + // + // Solution: Remove settings entirely from update requests.
