Connecting conversational AI to Alexa

问题

I built my Conversational AI chatbot and followed all the steps to connect it to Alexa but when I try to call my chatbot in alexa simulator,I get the following message:

"There was a problem with the requested skill's response"

this is the code which appears on JSON output 1 and JSON output 2 after the error:
