---
## 4. Error Handling Verification
### Compiled Code Analysis
Verified the following error handling improvements are deployed:
✅ **Rate Limit Handling** (HTTP 429):
- Detection: Response status 429 OR 403 with "rate" in message
- Retry-After header parsing
- Graceful degradation
- User-friendly error messages
✅ **Authentication Errors** (HTTP 401/403):
```
type: "AUTH_ERROR"
message: "Authentication failed (code): Token may be invalid or revoked"
statusCode: 401/403
```
✅ **Expired Sync Token** (HTTP 410):
```
type: "EXPIRED_SYNC_TOKEN"
message: "Sync token expired, full sync required"
```
✅ **Network Errors**:
- Timeout detection (30 second timeout)
- Connection failure handling
- Retry logic with backoff
✅ **Generic Error Handling**:
- Comprehensive error type mapping
- Stack trace logging for debugging
- User-friendly error messages
- Preserves error context
---
## 5. Startup Logs
### PM2 Logs Analysis
```bash
pm2 logs mcp-memory-web --lines 50
```
**Log Summary**:
- ✅ Clean startup
- ✅ No errors during initialization
- ✅ Next.js started on port 3001
- ✅ No warning messages
- ✅ No crash or restart loops
**Recent log entries**:
```
> mcp-memory-web@1.3.0 start
> next start -p 3001
```

## 6. Deployment Evidence
### Build Artifacts
- Location: `/Users/masa/Projects/mcp-memory-ts/web/.next/`
- Size: Production optimized
- Compilation mode: `compile`
- All routes finalized successfully
### Error Handling Code Verification
Confirmed error handling patterns in compiled JavaScript:
- ✅ Rate limit detection: `429 === b || 403 === b && a.message?.includes("rate")`
- ✅ Auth error detection: `401 === b || 403 === b`
- ✅ Sync token expiry: `410 === b || a.message?.includes("Sync token expired")`
- ✅ Network timeout: `a.message?.includes("timed out")`

## 9. Error Handling Improvements Deployed
### Rate Limit Errors (HTTP 429)
**Before**: Generic error message, no retry guidance
**After**:
- Detects rate limit errors (429 OR 403 with "rate")
- Parses Retry-After header
- Returns structured error with retry timing
- User-friendly message: "Rate limit exceeded, retry after Xs"
### Authentication Errors (HTTP 401/403)
**Before**: Unclear error messages
**After**:
- Clear AUTH_ERROR type
- Detailed message with status code
- Suggests token may be invalid or revoked
- Helps users diagnose OAuth issues
### Expired Sync Token (HTTP 410)
**Before**: May have caused crash or unclear error
**After**:
- Specific EXPIRED_SYNC_TOKEN type
- Clear message about sync token expiry
- Triggers full sync fallback
- Prevents sync failures
### Network Timeouts
**Before**: Undefined timeout behavior
**After**:
- 30-second timeout on all API calls
- Timeout detection and handling
- Clear timeout error messages
- Retry mechanism support
### Generic Errors
**Before**: May lose error context
**After**:
- Comprehensive error logging
- Stack trace capture
- Status code preservation
- Error type classification

## 10. Testing Recommendations
### Manual Testing
1. **Authenticated User**:
- Log in via Clerk authentication
- Navigate to Google sync page
- Test sync with valid Google connection
2. **Rate Limit Testing**:
- Trigger multiple rapid sync requests
- Verify rate limit error handling
- Check Retry-After messaging
3. **Authentication Testing**:
- Test with expired Google token
- Verify auth error messages
- Test re-authentication flow
4. **Network Testing**:
- Test with slow connection
- Verify timeout handling
- Check error recovery
### Monitoring
- Monitor PM2 logs: `pm2 logs mcp-memory-web`
- Check for error patterns
- Track sync success rates
- Monitor memory and CPU usage
---
## 11. Rollback Plan
If issues are detected:
```bash
# 1. Stop current server
pm2 stop mcp-memory-web
# 2. Revert to previous build
cd /Users/masa/Projects/mcp-memory-ts
git checkout HEAD~1 web/
# 3. Rebuild
cd web && npm run build
# 4. Restart
pm2 restart mcp-memory-web
```
