Responses not Generated - No Memorised Next action

I am working with the basic RASA Tutorials

My Problem Definition:

I have 3 basic intents - greet / thankyou/ Flight_Options Story - Greet --> Flight_Option --> Thank you My response for Flight_options has 2 slots - FromCity and ToCity I train my core and NLU I initiate the model with python -m rasa_core.run -d models/dialogue -u models/current/nlu

  1. When I provide an input - the NER happens perfectly ( which I can see in the debug mode) But I get the issue of NO next memorized action

Ex: I want to fly from New York to London --> Slots are extracted which can be viewed in debug --> But says no next memorized action I have tried max_history and augmentation but it has not worked so far I would like to understand what the problem is

  1. When I provide an input WITHOUT SLOT VALUES - The Intent is identified and the response is provided

Ex: Input -" I want to fly" --> intent Identified --> Response is " Here are your Flight options from None to None" Which is supposed to be " Here are your Flight options from (FromCity) to (ToCity)" Since slot values are not present. This response is valid

Could some one point me to why this is happening?
