Intent is not fulfilling after Confirmation propmt - amazon-lex

Question

I am working on lexing and want to fulfill the intent when all slot values are filled. But the intent is not fulfilling after the confirmation prompt. it is asking, again and again, a Confirmation prompt but not fulfilling the intent. I have code in python So please check if there is anything wrong in my code. Thanks.
see screenshot.
I am also attaching the code please check.

If you're using the same Lambda function for both validation and fulfillment, you would need to check the invocationSource and decide how to proceed accordingly. Since intent confirmation is also enabled, also use the confirmationStatus parameter to know whether the user confirmed or denied the prompt.
Check the input event format for the JSON structure passed by Lex to the codehook Lambda: https://docs.aws.amazon.com/lex/latest/dg/lambda-input-response-format.html#using-lambda-input-event-format
