Hello Srikanth,
Thank you for your question. You can run with rasa shell --debug and see what is going wrong. Unfortunately, it is quite hard to check your code since it is pasted as a text. A good tip is to denote your code with these brackets </> (it is a button option when you write your question) or code format with ``` like mentioned here.
Also, in case you have more slots and more complicated actions you can consider using Forms.
