Rasa Wellness bot update to v2.4.x struggle [Closed]

[kmanadkat (Krupesh Anadkat)]

I am beginner in rasa chatbot things. I am following Rasa for Beginners Udemy course The course is outdated, so I am trying my best to update things, I am stuck at Forms

After watching some latest Forms tutorials in Rasa Youtube official channel & following RasaHQ/rasa/examples/formbot github example, I was able to create Form with slots mapping

I even learnt how to activate & deactivate forms from this migration doc

But my setup its not working , let me show problems below (I was running rasa in interactive mode, to debug things):

Full code in github. For quick glance:

Just 1 thing is left, I need to skip exercise slot if confirm_exercise is false… searching for examples and old posts in this forum. If someone bump into this thread, please feel free to add anything you know

I was able to finally complete this, I added below stuff in actions.py after reading docs, referring this example & thanks to @marcos.allysson for this answer

from typing import Text, List

from rasa_sdk import Tracker, FormValidationAction
from rasa_sdk.executor import CollectingDispatcher
from rasa_sdk.types import DomainDict

class ValidateHealthForm(FormValidationAction):

  def name(self) -> Text:
      return "validate_health_form"

  async def required_slots(
    self,
    slots_mapped_in_domain: List[Text],
    dispatcher: "CollectingDispatcher",
    tracker: "Tracker",
    domain: "DomainDict"
  ) -> List[Text]:
    if tracker.get_slot("confirm_exercise") == True:
      return ["confirm_exercise", "exercise", "sleep", "diet", "stress", "goal"]
    else:
      return ["confirm_exercise", "sleep", "diet", "stress", "goal"]

after this I uncommented 2 lines in endpoints.yml most likely this is for telling rasa where to send requests for checking custom actions. (correct me if i am wrong)

action_endpoint:
 url: "http://localhost:5055/webhook"

finally in domain.yml file I added below stuff just before form definition.

actions:
- validate_health_form

Note : The purpose of this thread to help a beginner fumbling across internet to understand & implement things in latest rasa sdk
