How to Reactivate forms in Rasa 3.1?

Rasa Open Source
1

Hi Team, I am trying to implement two usecases where I am taking user input via forms & slots implementation and then validate user input via custom action. After validating I am trying to pull the information from python API via custom action. I have implemented flow in rules rather in stories for these usecases as per rasa documentation. It works as expected when I first time call the intent , it asks for user input and sets the slots but when next time in same session if I call same intent I get previous response, It doesn’t ask for user inputs. Here are the snippet and respective files.

Chat: Your input → server information XXXX

Please proceed with server_information

Looking for server_information XXXXX

(Get the proper response)

Your input → server info

Please proceed with server_information

Looking for server_information XXXXXX // Here it should ask me to provide the server name (Get previous response)

nlu.yml:

  • intent: server_information

    examples: |

    • server xxxxxxx information

    • server xxxxxxx details

    • server xxxxxxx info

    • db server xxxxxx details

    • db server xxxxxxx info

    • db server xxxxxx](server_name) information

    • database xxxxxx](server_name) server information

Please suggest if this is normal behavior of rasa or something is missing.

I resolved this issue by below implementation in actions implementation.

       if not tracker.slots["requested_slot"] == "server_name" :
          return {"server_name": None}
        else:    
          return {"server_name": tracker.get_slot('server_name')}
