Auf meinem Testsystem mit der identischen Konfiguration funktioniert die Emailbenachrichtigung/Event problemlos. **Der einzige Unterschied zu dem System das den Fehler auswirft ist die php version,:7.3.12**.  
Das funktionierende System läuft mit php 7.4.5.

Wir haben seit ca 3 Wochen den selben Fehler auf unserem System. Allerdings werden EMailbenachrichtigungen ausgegeben. Begonnen hat die Fehlermeldung meiner Meinung nach, nachdem ein Termin der bereits verstrichen war in ein zukünftiges Datum geändert und eine Emailbenachrichtigung hinzugefügt wurde. Die Benachrichtigung funktionierte hier nicht. Neue Termine liefern eine Benachrichtigung. NC und PHP sind auf dem neuesten Stand. Es gibt sonst keinerlei Einschränkungen in den Funktionen. Nur alle 10 min folgende Fehlermeldung in der log:
