## [2.18.6] - 2025-10-10
|
||||
|
||||
### 🐛 Bug Fixes
|
||||
|
||||
**PR #303: Environment-Aware Debugging Test Fix**
|
||||
|
||||
This release fixes a unit test failure that occurred after implementing environment-aware debugging improvements. The handleHealthCheck error handler now includes troubleshooting guidance in error responses, and the test expectations have been updated to match.
|
||||
|
||||
#### Fixed
|
||||
|
||||
- **Unit Test Failure in handleHealthCheck**
|
||||
- **Issue**: Test expected error response without `troubleshooting` array field
|
||||
- **Impact**: CI pipeline failing on PR #303 after adding environment-aware debugging
|
||||
- **Root Cause**: Environment-aware debugging improvements added a `troubleshooting` array to error responses, but unit test wasn't updated
|
||||
- **Fix**: Updated test expectation to include the new troubleshooting field (lines 1030-1035 in `tests/unit/mcp/handlers-n8n-manager.test.ts`)
|
||||
- **Error Response Structure** (now includes):
|
||||
```typescript
|
||||
details: {
|
||||
apiUrl: 'https://n8n.test.com',
|
||||
hint: 'Check if n8n is running and API is enabled',
|
||||
troubleshooting: [
|
||||
'1. Verify n8n instance is running',
|
||||
'2. Check N8N_API_URL is correct',
|
||||
'3. Verify N8N_API_KEY has proper permissions',
|
||||
'4. Run n8n_diagnostic for detailed analysis'
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
#### Testing
|
||||
|
||||
- **Unit Test**: Test now passes with troubleshooting array expectation
|
||||
- **MCP Testing**: Extensively validated with n8n-mcp-tester agent
|
||||
- Health check successful connections: ✅
|
||||
- Error responses include troubleshooting guidance: ✅
|
||||
- Diagnostic tool environment detection: ✅
|
||||
- Mode-specific debugging (stdio/HTTP): ✅
|
||||
- All environment-aware debugging features working correctly: ✅
|
||||
|
||||
#### Impact
|
||||
|
||||
- **CI Pipeline**: PR #303 now passes all tests
|
||||
- **Error Guidance**: Users receive actionable troubleshooting steps when API errors occur
|
||||
- **Environment Detection**: Comprehensive debugging guidance based on deployment environment
|
||||
- **Zero Breaking Changes**: Only internal test expectations updated
|
||||
|
||||
#### Related
|
||||
|
||||
- **PR #303**: feat: Add environment-aware debugging to diagnostic tools
|
||||
- **Implementation**: `src/mcp/handlers-n8n-manager.ts` lines 1447-1462
|
||||
- **Diagnostic Tool**: Enhanced with mode-specific, Docker-specific, and cloud platform-specific debugging
