Hallo Community,
ich habe mir folgendes Buch bei Amazon gekauft: Einstieg in die Alexa Skill Entwicklung für Echo (Dot): Mit Beispielen in node.js Kindle Edition.

Leider funktioniert der erste Skill nicht, da ich immer die folgende Fehlermeldung bekomme:

Hat jemand eine Idee, was schief läuft?

Achso: der Originalcode sieht so aus:
