Trouble with Amazon Lex chatbot slots

I am trying to create a chatbot. Chatbot will prompt the question "What is your nationality? (A, B, C)" and if the user says C, I want to straight away end the chat by saying something like "I am sorry, C is not applicable to apply. Only A and B can apply." I know I have to uncheck the "required" checkbox after the said question but I'm not sure what to input in aws lambda for it to happen.

enter image description here

Solution

  • After unchecking the required checkbox, in the lambda code do below:

    # inside dialogcodehook
slots = intent_request['currentIntent']['slots']
nation = slots['nation']
if nation == 'C':
    return close('I am sorry, C is not applicable to apply. Only A and B can apply.')
# rest of your code

def close(msg):
"dialogAction": {
    "type": "Close",
    "fulfillmentState": "Fulfilled",
    "message": {
      "contentType": "PlainText",
      "content": msg
    }
}

    Play with it and see documentation for other things and comment for further doubts.

    Hope it helps.
