PR Summary

• Improved Usage of ErrorListener An update to the product makes it possible to use the ErrorListener feature even when a logger is not available. This enhancement provides more flexibility as it caters for scenarios where the logger may not be necessary.

• Enhanced ErrorListener Construction and Error Logging The mechanism through which the ErrorListener is constructed has been altered. Now, the system can cope with situations where the logging parameter is null. Furthermore, before logging an error, the system checks if the logger is null. This ensures we avoid complications that may arise from attempts to log without a logger.
