def lambda_handler(event, context):
entity = event["currentIntent"]["slots"]["Name"].title()
intent = event["currentIntent"]["name"]
response = {
"sessionAttributes": {
"key1": "value1",
"key2": "value2"
},
"dialogAction":
{
"fulfillmentState":"Fulfilled",
"type":"Close",
"message":
{
"contentType":"PlainText",
"content": "The intent you are in now is "+intent+"!"
}
}
}
return response
