for a missing license (say, product is only WAF licensed), the library is not gracefully treating errors

Beginnen Sie bei export_to_json in MxConnection.py und verfolgen Sie den Traceback durch core.py, ServerGroup.py und DbService.py, um die Antwort auf das nicht lizenzierte Feature zu reproduzieren. Bestimmen Sie die erwartete ordnungsgemäße Behandlung für IMP-10129 und überprüfen Sie, dass der Exportpfad nicht mehr mit dem gezeigten unbehandelten Fehler fehlschlägt.
