Implement Phase 3: Enhanced Error Handling
This commit implements Phase 3 of the Sacred Pipeline, focusing on enhanced error handling. It includes: - **Transaction Status Polling Endpoint**: A new edge function `check-transaction-status` allows clients to poll the status of moderation transactions using idempotency keys. - **Expanded Error Sanitizer Patterns**: The `src/lib/errorSanitizer.ts` file has been updated with more comprehensive patterns to remove sensitive information from error messages, making them safer for display and logging. User-friendly replacements for common errors are also included. - **Rate Limiting for Submission Creation**: Client-side rate limiting has been implemented in `src/lib/submissionRateLimiter.ts` and applied to key submission functions within `src/lib/entitySubmissionHelpers.ts` (e.g., `submitParkCreation`, `submitRideCreation`, `submitParkUpdate`, `submitRideUpdate`) to prevent abuse and accidental duplicate submissions.

# Phase 3: Enhanced Error Handling - COMPLETE
|
||||
|
||||
**Status**: ✅ Fully Implemented
|
||||
**Date**: 2025-01-07
|
||||
|
||||
## Overview
|
||||
|
||||
Phase 3 adds comprehensive error handling improvements to the Sacred Pipeline, including transaction status polling, enhanced error sanitization, and client-side rate limiting for submission creation.
|
||||
|
||||
## Components Implemented
|
||||
|
||||
### 1. Transaction Status Polling Endpoint
|
||||
|
||||
**Edge Function**: `check-transaction-status`
|
||||
**Purpose**: Allows clients to poll the status of moderation transactions using idempotency keys
|
||||
|
||||
**Features**:
|
||||
- Query transaction status by idempotency key
|
||||
- Returns detailed status information (pending, processing, completed, failed, expired)
|
||||
- User authentication and authorization (users can only check their own transactions)
|
||||
- Structured error responses
|
||||
- Comprehensive logging
|
||||
|
||||
**Usage**:
|
||||
```typescript
|
||||
const { data, error } = await supabase.functions.invoke('check-transaction-status', {
|
||||
body: { idempotencyKey: 'approval_submission123_...' }
|
||||
});
|
||||
|
||||
// Response includes:
|
||||
// - status: 'pending' | 'processing' | 'completed' | 'failed' | 'expired' | 'not_found'
|
||||
// - createdAt, updatedAt, expiresAt
|
||||
// - attempts, lastError (if failed)
|
||||
// - action, submissionId
|
||||
```
|
||||
|
||||
**API Endpoints**:
|
||||
- `POST /check-transaction-status` - Check status by idempotency key
|
||||
- Requires: Authentication header
|
||||
- Returns: StatusResponse with transaction details
|
||||
|
||||
### 2. Error Sanitizer
|
||||
|
||||
**File**: `src/lib/errorSanitizer.ts`
|
||||
**Purpose**: Removes sensitive information from error messages before display or logging
|
||||
|
||||
**Sensitive Patterns Detected**:
|
||||
- Authentication tokens (Bearer, JWT, API keys)
|
||||
- Database connection strings (PostgreSQL, MySQL)
|
||||
- Internal IP addresses
|
||||
- Email addresses in error messages
|
||||
- UUIDs (internal IDs)
|
||||
- File paths (Unix & Windows)
|
||||
- Stack traces with file paths
|
||||
- SQL queries revealing schema
|
||||
|
||||
**User-Friendly Replacements**:
|
||||
- Database constraint errors → "This item already exists", "Required field missing"
|
||||
- Auth errors → "Session expired. Please log in again"
|
||||
- Network errors → "Service temporarily unavailable"
|
||||
- Rate limiting → "Rate limit exceeded. Please wait before trying again"
|
||||
- Permission errors → "Access denied"
|
||||
|
||||
**Functions**:
|
||||
- `sanitizeErrorMessage(error, context?)` - Main sanitization function
|
||||
- `containsSensitiveData(message)` - Check if message has sensitive data
|
||||
- `sanitizeErrorForLogging(error)` - Sanitize for external logging
|
||||
- `createSafeErrorResponse(error, fallbackMessage?)` - Create user-safe error response
|
||||
|
||||
**Examples**:
|
||||
```typescript
|
||||
import { sanitizeErrorMessage } from '@/lib/errorSanitizer';
|
||||
|
||||
try {
|
||||
// ... operation
|
||||
} catch (error) {
|
||||
const safeMessage = sanitizeErrorMessage(error, {
|
||||
action: 'park_creation',
|
||||
userId: user.id
|
||||
});
|
||||
|
||||
toast({
|
||||
title: 'Error',
|
||||
description: safeMessage,
|
||||
variant: 'destructive'
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Submission Rate Limiting
|
||||
|
||||
**File**: `src/lib/submissionRateLimiter.ts`
|
||||
**Purpose**: Client-side rate limiting to prevent submission abuse and accidental duplicates
|
||||
|
||||
**Rate Limits**:
|
||||
- **Per Minute**: 5 submissions maximum
|
||||
- **Per Hour**: 20 submissions maximum
|
||||
- **Cooldown**: 60 seconds after exceeding limits
|
||||
|
||||
**Features**:
|
||||
- In-memory rate limit tracking (per session)
|
||||
- Automatic timestamp cleanup
|
||||
- User-specific limits
|
||||
- Cooldown period after limit exceeded
|
||||
- Detailed logging
|
||||
|
||||
**Integration**: Applied to all submission functions in `entitySubmissionHelpers.ts`:
|
||||
- `submitParkCreation`
|
||||
- `submitParkUpdate`
|
||||
- `submitRideCreation`
|
||||
- `submitRideUpdate`
|
||||
- Composite submissions
|
||||
|
||||
**Functions**:
|
||||
- `checkSubmissionRateLimit(userId, config?)` - Check if user can submit
|
||||
- `recordSubmissionAttempt(userId)` - Record a submission (called after success)
|
||||
- `getRateLimitStatus(userId)` - Get current rate limit status
|
||||
- `clearUserRateLimit(userId)` - Clear limits (admin/testing)
|
||||
|
||||
**Usage**:
|
||||
```typescript
|
||||
// In entitySubmissionHelpers.ts
|
||||
function checkRateLimitOrThrow(userId: string, action: string): void {
|
||||
const rateLimit = checkSubmissionRateLimit(userId);
|
||||
|
||||
if (!rateLimit.allowed) {
|
||||
throw new Error(sanitizeErrorMessage(rateLimit.reason));
|
||||
}
|
||||
}
|
||||
|
||||
// Called at the start of every submission function
|
||||
export async function submitParkCreation(data, userId) {
|
||||
checkRateLimitOrThrow(userId, 'park_creation');
|
||||
// ... rest of submission logic
|
||||
}
|
||||
```
|
||||
|
||||
**Response Example**:
|
||||
```typescript
|
||||
{
|
||||
allowed: false,
|
||||
reason: 'Too many submissions in a short time. Please wait 60 seconds',
|
||||
retryAfter: 60
|
||||
}
|
||||
```
|
||||
|
||||
## Architecture Adherence
|
||||
|
||||
✅ **No JSON/JSONB**: Error sanitizer operates on strings, rate limiter uses in-memory storage
|
||||
✅ **Relational**: Transaction status queries the `idempotency_keys` table
|
||||
✅ **Type Safety**: Full TypeScript types for all interfaces
|
||||
✅ **Logging**: Comprehensive structured logging for debugging
|
||||
|
||||
## Security Benefits
|
||||
|
||||
1. **Sensitive Data Protection**: Error messages no longer expose internal details
|
||||
2. **Rate Limit Protection**: Prevents submission flooding and abuse
|
||||
3. **Transaction Visibility**: Users can check their own transaction status safely
|
||||
4. **Audit Trail**: All rate limit events logged for security monitoring
|
||||
|
||||

### Core Implementation
|
||||
- `supabase/functions/check-transaction-status/index.ts` - Transaction polling endpoint
|
||||
- `src/lib/errorSanitizer.ts` - Error message sanitization
|
||||
- `src/lib/submissionRateLimiter.ts` - Client-side rate limiting
|
||||
- `src/lib/entitySubmissionHelpers.ts` - Integrated rate limiting
|
||||
|
||||
### Dependencies
|
||||
- `src/lib/idempotencyLifecycle.ts` - Idempotency key lifecycle management
|
||||
- `src/lib/logger.ts` - Structured logging
|
||||
- `supabase/functions/_shared/logger.ts` - Edge function logging
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
1. **In-Memory Storage**: Rate limiter uses Map for O(1) lookups
|
||||
2. **Automatic Cleanup**: Old timestamps removed on each check
|
||||
3. **Minimal Overhead**: Pattern matching optimized with pre-compiled regexes
|
||||
4. **Database Queries**: Transaction status uses indexed lookup on idempotency_keys.key
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
Potential improvements for future phases:
|
||||
|
||||
1. **Persistent Rate Limiting**: Store rate limits in database for cross-session tracking
|
||||
2. **Dynamic Rate Limits**: Adjust limits based on user reputation/role
|
||||
3. **Advanced Sanitization**: Context-aware sanitization based on error types
|
||||
4. **Error Pattern Learning**: ML-based detection of new sensitive patterns
|
||||
5. **Transaction Webhooks**: Real-time notifications when transactions complete
|
||||
6. **Rate Limit Dashboard**: Admin UI to view and manage rate limits
|
||||
|
||||
## API Reference
|
||||
|
||||
### Check Transaction Status
|
||||
|
||||
**Endpoint**: `POST /functions/v1/check-transaction-status`
|
||||
|
||||
**Request**:
|
||||
```json
|
||||
{
|
||||
"idempotencyKey": "approval_submission_abc123_..."
|
||||
}
|
||||
```
|
||||
|
||||
**Response** (200 OK):
|
||||
```json
|
||||
{
|
||||
"status": "completed",
|
||||
"createdAt": "2025-01-07T10:30:00Z",
|
||||
"updatedAt": "2025-01-07T10:30:05Z",
|
||||
"expiresAt": "2025-01-08T10:30:00Z",
|
||||
"attempts": 1,
|
||||
"action": "approval",
|
||||
"submissionId": "abc123",
|
||||
"completedAt": "2025-01-07T10:30:05Z"
|
||||
}
|
||||
```
|
||||
|
||||
**Response** (404 Not Found):
|
||||
```json
|
||||
{
|
||||
"status": "not_found",
|
||||
"error": "Transaction not found. It may have expired or never existed."
|
||||
}
|
||||
```
|
||||
|
||||
**Response** (401/403):
|
||||
```json
|
||||
{
|
||||
"error": "Unauthorized",
|
||||
"status": "not_found"
|
||||
}
|
||||
```
|
||||
|
||||
## Migration Notes
|
||||
|
||||
No database migrations required for this phase. All functionality is:
|
||||
- Edge function (auto-deployed)
|
||||
- Client-side utilities (imported as needed)
|
||||
- Integration into existing submission functions
|
||||
|
||||
## Monitoring
|
||||
|
||||
Key metrics to monitor:
|
||||
|
||||
1. **Rate Limit Events**: Track users hitting limits
|
||||
2. **Sanitization Events**: Count messages requiring sanitization
|
||||
3. **Transaction Status Queries**: Monitor polling frequency
|
||||
4. **Error Patterns**: Identify common sanitized error types
|
||||
|
||||
Query examples in admin dashboard:
|
||||
```sql
|
||||
-- Rate limit violations (from logs)
|
||||
SELECT COUNT(*) FROM request_metadata
|
||||
WHERE error_message LIKE '%Rate limit exceeded%'
|
||||
GROUP BY DATE(created_at);
|
||||
|
||||
-- Transaction status queries
|
||||
-- (Check edge function logs for check-transaction-status)
|
||||
```
|
||||
|
||||
