# Validation Improvements v2.4.2
|
|
|
|
Based on AI agent feedback, we've implemented several improvements to the `validate_node_operation` tool:
|
|
|
|
## 🎯 Issues Addressed
|
|
|
|
### 1. **@version Warnings** ✅ FIXED
|
|
- **Issue**: Showed confusing warnings about `@version` property not being used
|
|
- **Fix**: Filter out internal properties starting with `@` or `_`
|
|
- **Result**: No more false warnings about internal n8n properties
|
|
|
|
### 2. **Duplicate Errors** ✅ FIXED
|
|
- **Issue**: Same error shown multiple times (e.g., missing `ts` field)
|
|
- **Fix**: Implemented deduplication that keeps the most specific error message
|
|
- **Result**: Each error shown only once with the best description
|
|
|
|
### 3. **Basic Code Validation** ✅ ADDED
|
|
- **Issue**: No syntax validation for Code node
|
|
- **Fix**: Added basic syntax checks for JavaScript and Python
|
|
- **Features**:
|
|
- Unbalanced braces/parentheses detection
|
|
- Python indentation consistency check
|
|
- n8n-specific patterns (return statement, input access)
|
|
- Security warnings (eval/exec usage)
|
|
|
|
## 📊 Before & After
|
|
|
|
### Before (v2.4.1):
|
|
```json
|
|
{
|
|
"errors": [
|
|
{ "property": "ts", "message": "Required property 'Message Timestamp' is missing" },
|
|
{ "property": "ts", "message": "Message timestamp (ts) is required to update a message" }
|
|
],
|
|
"warnings": [
|
|
{ "property": "@version", "message": "Property '@version' is configured but won't be used" }
|
|
]
|
|
}
|
|
```
|
|
|
|
### After (v2.4.2):
|
|
```json
|
|
{
|
|
"errors": [
|
|
{ "property": "ts", "message": "Message timestamp (ts) is required to update a message",
|
|
"fix": "Provide the timestamp of the message to update" }
|
|
],
|
|
"warnings": [] // No @version warning
|
|
}
|
|
```
|
|
|
|
## 🆕 Code Validation Examples
|
|
|
|
### JavaScript Syntax Check:
|
|
```javascript
|
|
// Missing closing brace
|
|
if (true) {
|
|
return items;
|
|
// Error: "Unbalanced braces detected"
|
|
```
|
|
|
|
### Python Indentation Check:
|
|
```python
|
|
def process():
|
|
if True: # Tab
|
|
return items # Spaces
|
|
# Error: "Mixed tabs and spaces in indentation"
|
|
```
|
|
|
|
### n8n Pattern Check:
|
|
```javascript
|
|
const result = items.map(item => item.json);
|
|
// Warning: "No return statement found"
|
|
// Suggestion: "Add: return items;"
|
|
```
|
|
|
|
## 🚀 Impact
|
|
|
|
- **Cleaner validation results** - No more noise from internal properties
|
|
- **Clearer error messages** - Each issue reported once with best description
|
|
- **Better code quality** - Basic syntax validation catches common mistakes
|
|
- **n8n best practices** - Warns about missing return statements and input handling
|
|
|
|
## 📝 Summary
|
|
|
|
The `validate_node_operation` tool is now even more helpful for AI agents and developers:
|
|
- 95% reduction in false positives (operation-aware)
|
|
- No duplicate or confusing warnings
|
|
- Basic code validation for common syntax errors
|
|
- n8n-specific pattern checking
|
