## [2.6.2] - 2025-06-26
|
||||
|
||||
### Added
|
||||
- **Enhanced Workflow Creation Validation**: Major improvements to prevent broken workflows
|
||||
- **NEW**: Node type existence validation - Verifies node types actually exist in n8n
|
||||
- **NEW**: Smart suggestions for common mistakes - Detects `webhook` and suggests `n8n-nodes-base.webhook`
|
||||
- **NEW**: Minimum viable workflow validation - Prevents single-node workflows (except webhooks)
|
||||
- **NEW**: Empty connection detection - Catches multi-node workflows with no connections
|
||||
- **NEW**: Helper functions - `getWorkflowStructureExample()` and `getWorkflowFixSuggestions()`
|
||||
- Enhanced error messages with clear guidance and connection examples
|
||||
- Prevents broken workflows that show as question marks in n8n UI
|
||||
|
||||
### Fixed
|
||||
- **Critical**: `nodes-base.webhook` validation - Now caught BEFORE database lookup
|
||||
- Previously, `nodes-base.webhook` would pass validation because it existed in the normalized database
|
||||
- Now explicitly checks for and rejects `nodes-base.` prefix before any database operations
|
||||
- This fixes the exact issue causing workflows to appear broken in n8n UI
|
||||
|
||||
### Changed
|
||||
- Workflow validator now checks node types in order: invalid patterns → database lookup → suggestions
|
||||
- Connection validation messages now include proper format examples
|
||||
- Error messages are more actionable with specific fix instructions
|
||||
|
||||
## [2.6.1] - 2025-06-26
|
||||
|
||||
### Added
|
||||
- **Enhanced typeVersion Validation**: Comprehensive validation for versioned nodes
|
||||
- **NEW**: typeVersion validation enforced on all versioned nodes
|
||||
- Catches missing typeVersion and provides correct version to use
|
||||
- Warns on outdated versions when newer versions are available
|
||||
- Prevents invalid versions that exceed maximum supported
|
||||
- Helps AI agents avoid common workflow creation mistakes
|
||||
- Test coverage for all typeVersion scenarios
|
||||
|
||||
### Changed
|
||||
- WorkflowValidator now includes typeVersion in its validation pipeline
|
||||
- Enhanced error messages for typeVersion issues with actionable suggestions
|
||||
|
||||
