Custom actions - passing data using slots

samitharuwan2 · May 11, 2022, 2:44pm

Hello, I’m new to the rasa. I developed a custom action and tried to pass data through slots. but it shows an error while running. It shows variable is the NoneType object. I think data is not passing through the slots. is there any wrong with my code?

Hi!

I think your code is right. I think this action are trigger before set any value in amount slot and trying make split in null value

Can you check it using print(UserReply) before the for loop?

If you prefer, you can use rasa FormValidationAction

RasaHQ/rasa-2.x-form-examples/blob/main/05-validation/actions/actions.py#L8

    
      
          from typing import Text, List, Any, Dict
          
          
from rasa_sdk import Tracker, FormValidationAction
          from rasa_sdk.executor import CollectingDispatcher
          from rasa_sdk.types import DomainDict
          
          

          
class ValidateNameForm(FormValidationAction):
              def name(self) -> Text:
                  return "validate_name_form"
          
          
    def validate_first_name(
                  self,
                  slot_value: Any,
                  dispatcher: CollectingDispatcher,
                  tracker: Tracker,
                  domain: DomainDict,
              ) -> Dict[Text, Any]:
