* fix: n8n_test_workflow webhookId resolution and form handling (v2.28.2) ## Bug Fixes - **webhookId Resolution**: Fixed trigger handlers using `node.id` instead of `node.webhookId` for building webhook URLs. This caused 404 errors when nodes had custom IDs. - **Chat Trigger URL**: Fixed chat triggers using wrong URL pattern. Now correctly uses `/webhook/<webhookId>/chat` endpoint. - **Form Content-Type**: Fixed form triggers failing with "Expected multipart/form-data" error by switching to proper multipart encoding. ## Enhancements - **Form Field Types**: Added support for all n8n form field types (text, textarea, email, number, password, date, dropdown, checkbox, file, hidden) - **Checkbox Arrays**: Automatically converts arrays to `field[]` format - **Helpful Warnings**: Reports missing required fields with names and labels - **Error Hints**: Provides complete field structure on failure Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: address code review issues for form trigger improvements - Add form-data as direct dependency (was only in devDependencies) - Add TypeScript interfaces (FormFieldValue, FormFieldOption) replacing any types - Add FORM_FIELD_TYPES constants for type-safe switch statements - Add isValidBase64() validation for file uploads with size limits - Add MAX_FILE_SIZE_BYTES (10MB) constant with validation - Update form-handler.test.ts for FormData instead of JSON - Update trigger-detector.test.ts for chat URL /chat suffix Conceived by Romuald Członkowski - www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * feat: configurable MAX_SESSIONS via N8N_MCP_MAX_SESSIONS env var (v2.28.3) (#468) Make MAX_SESSIONS limit configurable for multi-tenant SaaS deployments. - Add N8N_MCP_MAX_SESSIONS environment variable (default: 100) - Include safety floor with Math.max(1, ...) to prevent invalid configs - Update documentation in LIBRARY_USAGE.md, SESSION_PERSISTENCE.md - Update CLAUDE.md and CHANGELOG.md Fixes #468 Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: add QEMU setup for multi-arch Docker builds Add docker/setup-qemu-action@v3 before Buildx setup to enable proper QEMU emulation for linux/arm64 builds on GitHub Actions.
