Beginnen Sie in SQLMonitor.java bei getConnectionProperties(SQLMonitor.java:113), und verfolgen Sie dann anhand des bereitgestellten Initialisierungs-Stacktraces createTask in Zeile 81 und doRun in Zeile 49. Identifizieren Sie, welcher Konfigurations- oder Verbindungswert null ist, und verifizieren Sie, dass die Monitorinitialisierung ohne diese Ausnahme abgeschlossen wird; im Issue wird kein Test- oder Reproduktions-Setup genannt.

Vom Indexierungsmodell aus dem Issue-Text verfasst.
