**Solution:**
- Wait for the rate limit window to reset
- Consider upgrading your GLEC API plan
- Implement request batching for bulk operations

#### 3. Network Connection Error
**Error:** `Network Error: Network connection failed`

**Solution:**
- Check your internet connection
- Verify the GLEC API is accessible
- Check firewall settings

#### 4. Validation Error
**Error:** `Validation Error: Invalid input parameters`

**Solution:**
- Check parameter types and values
- Ensure required parameters are provided
- Verify parameter ranges and formats

### Debug Mode

Enable debug logging to troubleshoot issues:

```json
{
  "env": {
    "LOG_LEVEL": "debug"
  }
}
```

### Logs

Logs are written to:
- Console output (for real-time debugging)
- `logs/error.log` (error logs)
- `logs/combined.log` (all logs)

## 📊 Performance

### Rate Limits

- **General API calls**: 100 requests/minute
- **Emission calculations**: 50 requests/minute
- **Report generation**: 10 requests/5 minutes
- **Shipper management**: 20 requests/minute

### Response Times

- **Emission calculations**: < 1 second
