c7da0a2430 fix: resolve YAML syntax error in release.yml workflow
Fixed invalid multi-line string syntax at line 148 by converting to heredoc.
The quoted multi-line string was breaking YAML parsing. Using heredoc (cat <<EOF)
is the proper way to handle multi-line strings in bash within GitHub Actions.

This resolves the CI failure on main branch.

### ✨ Enhancements
**Issue #361: Enhanced HTTP Request Node Validation Suggestions**
Added helpful suggestions for HTTP Request node best practices to prevent common production issues discovered through real-world workflow analysis.
#### What's New
1. **alwaysOutputData Suggestion**
- Suggests adding `alwaysOutputData: true` at node level (not in parameters)
- Prevents silent workflow failures when HTTP requests error
- Ensures downstream error handling can process failed requests
- Example suggestion: "Consider adding alwaysOutputData: true at node level for better error handling. This ensures the node produces output even when HTTP requests fail, allowing downstream error handling."
2. **responseFormat Suggestion for API Endpoints**
- Suggests setting `options.response.response.responseFormat` for API endpoints
- Prevents JSON parsing confusion
- Triggered when URL contains `/api`, `/rest`, `supabase`, `firebase`, `googleapis`, or `.com/v` patterns
- Example suggestion: "API endpoints should explicitly set options.response.response.responseFormat to 'json' or 'text' to prevent confusion about response parsing"
3. **Enhanced URL Protocol Validation**
- Detects missing protocol in expression-based URLs
- Warns about patterns like `=www.{{ $json.domain }}.com` (missing http://)
- Warns about expressions without protocol: `={{ $json.domain }}/api/data`
- Example warning: "URL expression appears to be missing http:// or https:// protocol"
#### Investigation Findings
This enhancement was developed after thorough investigation of issue #361:
**Key Discoveries:**
- ✅ Mixed expression syntax `=literal{{ expression }}` **actually works in n8n** - the issue report's primary claim was incorrect
- ✅ Real validation gaps identified: missing `alwaysOutputData` and `responseFormat` checks
- ✅ Workflow analysis showed "?" icon in UI caused by missing required URL (already caught by validation)
- ✅ Compared broken vs fixed workflows to identify actual production issues
**Testing Evidence:**
- Analyzed workflow SwjKJsJhe8OsYfBk with mixed syntax - executions successful
- Compared broken workflow (mBmkyj460i5rYTG4) with fixed workflow (hQI9pby3nSFtk4TV)
- Identified that fixed workflow has `alwaysOutputData: true` and explicit `responseFormat: "json"`
#### Impact
- **Non-Breaking**: All changes are suggestions/warnings, not errors
- **Profile-Aware**: Suggestions shown in all profiles for maximum helpfulness
- **Actionable**: Clear guidance on how to implement best practices
- **Production-Focused**: Addresses real workflow reliability concerns from actual broken workflows
#### Test Coverage
Added 8 new test cases covering:
- alwaysOutputData suggestion for all HTTP Request nodes
- responseFormat suggestion for API endpoint detection (various patterns)
- responseFormat NOT suggested when already configured
- URL protocol validation for expression-based URLs
- Protocol warnings for missing http:// in expressions
- No false positives when protocol is correctly included
#### Technical Details
**Files Modified:**
- `src/services/enhanced-config-validator.ts` - Added `enhanceHttpRequestValidation()` implementation
- `tests/unit/services/enhanced-config-validator.test.ts` - Added 8 comprehensive test cases
**Validation Flow:**
1. Check for alwaysOutputData suggestion (all HTTP Request nodes)
2. Detect API endpoints by URL patterns
3. Check for explicit responseFormat configuration
4. Validate expression-based URLs for protocol issues
#### Related
- **Issue**: #361 - validate_node_operation: Missing critical HTTP Request node configuration checks
- **Analysis**: Deep investigation with @agent-Explore and @agent-n8n-mcp-tester
- **Workflows Analyzed**:
- SwjKJsJhe8OsYfBk (mixed syntax test)
- mBmkyj460i5rYTG4 (broken workflow)
- hQI9pby3nSFtk4TV (fixed workflow)

### 🐛 Bug Fixes
**Issue #360: Enhanced Warnings for If/Switch Node Connection Parameters**
Fixed issue where users could unintentionally place multiple If node connections on the same branch (TRUE/FALSE) when using `sourceIndex` parameter instead of the recommended `branch` parameter. The system now provides helpful warnings to guide users toward better practices.
#### What Was Fixed
1. **New Warning System**:
- Warns when using `sourceIndex` with If nodes - suggests `branch="true"` or `branch="false"` instead
- Warns when using `sourceIndex` with Switch nodes - suggests `case=N` instead
- Explains the correct branch structure: `main[0]=TRUE branch, main[1]=FALSE branch`
2. **Enhanced Documentation**:
- Added **CRITICAL** pitfalls to `n8n_update_partial_workflow` tool documentation
- Clear guidance that using `sourceIndex=0` for multiple connections puts them ALL on the TRUE branch
- Examples showing correct vs. incorrect usage
3. **Type System Improvements**:
- Added `warnings` field to `WorkflowDiffResult` interface
- Warnings are non-blocking (operations still succeed)
- Differentiated from errors for better UX
#### Behavior
The existing `branch` parameter works correctly and has comprehensive test coverage:
- `branch="true"` → routes to `main[0]` (TRUE path)
- `branch="false"` → routes to `main[1]` (FALSE path)
The issue was that users who didn't know about the `branch` parameter would naturally use `sourceIndex`, which led to incorrect branch routing.
#### Example Warning
```
Connection to If node "Check Condition" uses sourceIndex=0.
Consider using branch="true" or branch="false" for better clarity.
If node outputs: main[0]=TRUE branch, main[1]=FALSE branch.
```
#### Test Coverage
- Added regression tests that reproduce the exact issue from #360
- Verify warnings are generated for If and Switch nodes
- Confirm existing smart parameter tests still pass
