java.lang.NullPointerException beim PDF-Import

Hallo zusammen,

die PDFs können jetzt zwar eingelesen werden, es kommt dann aber beim Speichern der erkannten Buchungen zu einer java.lang.NullPointerException. Durch den Import sollten Buchungen die automatisch durch einen Wertpapier-Sparplan angelegt wurden, ersetzt werden.
Wenn ich die Buchungen die durch den Sparplan angelegt wurden vor dem Import lösche, funktioniert der Import auch problemlos.
Importiert wurden PDFs der Consorsbank. Falls weitere Informationen benötigt werden, bitte kurz bescheid geben.

Hier noch der Stacktrace:
