Lambda Hook for Amazon Lex V2 Book Trip Blueprint

This project provides a sample Python Lambda Hook, that is compatible with the Amazon Lex V2 data structure, and can be used with the Book Trip Blueprint that is described in the “Bot Examples” section of the Amazon Lex Developers Guide (https://docs.aws.amazon.com/lex/latest/dg/ex-book-trip.html). This Lambda Hook can be invoked at the Fulfillment section of both intents included in the bot configuration (BookHotel and BookCar), as well as an initialization and validation function at each turn of the dialog. It includes a sample json to be configured as Test Event for the Lambda Hook, simulating the payload that will be sent by Amazon Lex, when invoking the function.

In the current version of this code, the fulfillment messages have been set in Spanish. The English version of the texts is commented in lines 442 and 517.

amazon-lex-v2-lambdahook-for-booktripbot's Issues

Running this example for BookHotel and an invalid city does't show the reason.

I have

1. created an example bot in Lex v2.
2. add the Lambda function
3. Activated the code-hook in BookHotel
4. run the Test Bot with the Lambda Funktion.

Asking for a Hotel with a invalid city like 'Hamburg', doesn't return the message "We currently do not support Hamburg as a valid destination. Can you try a different city?"

close function not working

there is a bug in close function

def close(session_attributes, active_contexts, fulfillment_state, intent, message):
response = {
'sessionState': {
'activeContexts':[{
'name': 'intentContext',
'contextAttributes': active_contexts,
'timeToLive': {
'timeToLiveInSeconds': 600,
'turnsToLive': 1
}
}],
'sessionAttributes': session_attributes,
'dialogAction': {
'type': 'Close',
},
'intent': intent
},
'messages': [message]
}

return response
