Alexa multipart prompt skill voice test Issue - alexa-skill

Question

I am trying to build a new simple re-prompt skill to plan a trip. Its working fine when testing on developer test via text command but on https://echosim.io, It responds only to 1st time after that the response is "Sorry I don't know that" all the time. Please suggest me what's wrong I am doing.
