Die API funktioniert hervorragend, wenn alle zurückgegebenen Eigenschaften Werte enthalten. Wenn einer von ihnen einen leeren Wert hat, beispielsweise keinen Home-Ordner, schlägt die API-Anfrage fehl und gibt stattdessen den Homepage-HTML-Code zurück. Beim Kompilieren treten keine Fehler auf, daher weiß ich nicht, was ich sonst noch versuchen soll.
Ich habe eine if- und else-Anweisung ausprobiert, um anzugeben, ob der Wert leer oder null ist, und dann diese Zeichenfolge einzufügen schlägt aber immer noch fehl.
Jeder Rat wäre toll, danke
