feat: add error mode for execution debugging with AI suggestions (#505)
* feat: add error mode for execution debugging with AI suggestions Add a new `mode='error'` option to n8n_executions action=get that's optimized for AI agents debugging workflow failures. This mode provides intelligent error extraction with 80-99% token savings compared to `mode='full'`. Key features: - Error Analysis: Extracts error message, type, node name, and parameters - Upstream Context: Samples input data from upstream node (configurable limit) - Execution Path: Shows node execution sequence from trigger to error - AI Suggestions: Pattern-based fix suggestions for common errors - Workflow Fetch: Optionally fetches workflow for accurate upstream detection New parameters for mode='error': - errorItemsLimit (default: 2) - Sample items from upstream node - includeStackTrace (default: false) - Full vs truncated stack trace - includeExecutionPath (default: true) - Include node execution path - fetchWorkflow (default: true) - Fetch workflow for upstream detection Token efficiency: - 11 items: ~11KB full vs ~3KB error (73% savings) - 1001 items: ~354KB full vs ~3KB error (99% savings) Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix: add security hardening to error-execution-processor - Add prototype pollution protection (block __proto__, constructor, prototype) - Expand sensitive data patterns (20+ patterns including JWT, OAuth, certificates) - Create recursive sanitizeData function for deep object sanitization - Apply sanitization to both nodeParameters and upstream sampleItems - Add comprehensive unit tests (42 tests, 96% coverage) Security improvements address code review findings: - Critical: Prototype pollution protection - Warning: Expanded sensitive data filtering - Warning: Nested data sanitization Concieved by Romuald Członkowski - www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> --------- Co-authored-by: Romuald Członkowski <romualdczlonkowski@MacBook-Pro-Romuald.local> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>

## [Unreleased]
|
||||
|
||||
## [2.31.0] - 2025-12-23
|
||||
|
||||
### Added
|
||||
|
||||
**New `error` Mode for Execution Debugging**
|
||||
|
||||
Added a new `mode='error'` option to `n8n_executions` action=get that's optimized for AI agents debugging workflow failures. This mode provides intelligent error extraction with 80-99% token savings compared to `mode='full'`.
|
||||
|
||||
**Key Features:**
|
||||
|
||||
- **Error Analysis**: Extracts error message, type, node name, and relevant parameters
|
||||
- **Upstream Context**: Samples input data from the node feeding into the error node (configurable limit)
|
||||
- **Execution Path**: Shows the node execution sequence from trigger to error
|
||||
- **AI Suggestions**: Pattern-based fix suggestions for common errors (missing fields, auth issues, rate limits, etc.)
|
||||
- **Workflow Fetch**: Optionally fetches workflow structure for accurate upstream detection
|
||||
|
||||
**New Parameters for `mode='error'`:**
|
||||
|
||||
- `errorItemsLimit` (default: 2) - Number of sample items from upstream node
|
||||
- `includeStackTrace` (default: false) - Include full vs truncated stack trace
|
||||
- `includeExecutionPath` (default: true) - Include node execution path
|
||||
- `fetchWorkflow` (default: true) - Fetch workflow for accurate upstream detection
|
||||
|
||||
**Token Efficiency:**
|
||||
|
||||
| Execution Size | Full Mode | Error Mode | Savings |
|
||||
|----------------|-----------|------------|---------|
|
||||
| 11 items | ~11KB | ~3KB | 73% |
|
||||
| 1001 items | ~354KB | ~3KB | 99% |
|
||||
|
||||
**AI Suggestion Patterns Detected:**
|
||||
|
||||
- Missing required fields
|
||||
- Authentication/authorization issues
|
||||
- Rate limiting
|
||||
- Network/connection errors
|
||||
- Invalid JSON format
|
||||
- Missing data fields
|
||||
- Type mismatches
|
||||
- Timeouts
|
||||
- Permission denied
|
||||
|
||||
**Usage Examples:**
|
||||
|
||||
```javascript
|
||||
// Basic error debugging
|
||||
n8n_executions({action: "get", id: "exec_123", mode: "error"})
|
||||
|
||||
// With more sample data
|
||||
n8n_executions({action: "get", id: "exec_123", mode: "error", errorItemsLimit: 5})
|
||||
|
||||
// With full stack trace
|
||||
n8n_executions({action: "get", id: "exec_123", mode: "error", includeStackTrace: true})
|
||||
```
