Ich habe eine Entität mit einer Verschlusstabelle und einem Repository neben dem Erstellen. Ich versuche ein grundlegendes Beispiel für das Erstellen eines Baumes, aber ich sehe, dass der Fehler kein Objekt vom Typ App \ Entity \ Diskussion \ Kommentar als Array beim Aufrufen von GetCompmentTreefordiscussion
Entität verwenden kann:
