First Skill, just the errorHandler

I wanted to code my first Alexa Skill, but my very first intent isn´t working properly. The error handler comes in and responds with: "Sorry, ..."

I wanted to make a darts calculator and the first intent should return: 

"Ok ${spieleranzahl} Spieler, wie viele Punkte sollen gespielt werden?"

in english:

"Ok ${numerOfPlayers} players, how many points are we going to play?"

This is my js Code, can somebody tell me what i´m doing wrong? (Please don´t mind the spacing issues down at the JSON)

// This sample demonstrates handling intents from an Alexa skill using the Alexa Skills Kit SDK (v2).
// Please visit https://alexa.design/cookbook for additional examples on implementing slots, dialog management,
// session persistence, api calls, and more.
const Alexa = require('ask-sdk-core');

const LaunchRequestHandler = {
    canHandle(handlerInput) {
        return Alexa.getRequestType(handlerInput.requestEnvelope) === 'LaunchRequest';
    },
    handle(handlerInput) {
        const speakOutput = 'Ok, mit wie vielen Spielern möchtest du spielen?';
        const repromtText = 'Nenne eine Spieleranzahl zwischen eins und vier.';
        return handlerInput.responseBuilder
            .speak(speakOutput)
            .reprompt(repromtText)
            .getResponse();
    }

    },
    handle(handlerInput) {

You're logging out the stack trace of where it failed, have you tried looking in your cloudwatch logs for the error as it will narrow down the line?

Though off hand I can see your slot is called Spieleranzahl but in your code when you try to access it you use spieleranzahl <- notice the lowercase 's'. The property name will be case sensitive so this could cause the error.

Here's the corrected handler:

//ErfasseSpieleranzahlHandler
const ErfasseSpieleranzahlHandler = {
    canHandle(handlerInput) {
        return Alexa.getRequestType(handlerInput.requestEnvelope) === 'IntentRequest'
            && Alexa.getIntentName(handlerInput.requestEnvelope) === 'ErfasseSpieleranzahl';
    },
    handle(handlerInput) {
        const spieleranzahl = handlerInput.requestEnvelope.request.intent.slots.Spieleranzahl.value;

        const speakOutput = `Ok ${spieleranzahl} Spieler, wie viele Punkte sollen gespielt werden?`;
        return handlerInput.responseBuilder
            .speak(speakOutput)
            //.reprompt(repromtText)
            .getResponse();
    }
};
