How to stop bot reply in form validation action

Hi,
I create a bot with some integration parts. In here I want validate a user input using backend integration. I wrote the form validation in a try-except block in python because I want to handle the exception.
In my scenario I want stop the bot reply when it occurs an exception. I tried as follows

try:
  #.. Integrations
  # ....
except Exception as e:
  dipaticher.utter_message(text="An exception Occured")
  return [(ConversationPaused()]

But after I execute this code when it occurs an exception it gives correct error message but It continues asking for next slots. And it also gives a warning log in action server as following.

/usr/local/lib/python3.6/site-packages/rasa_sdk/forms.py:875: UserWarning: Cannot validate `name`: make sure the validation method returns the correct output.
  f"Cannot validate `{slot_name}`: make sure the validation method "

I want to stop the bot after an exception with giving an error message in a FormValidationAction. How can I do this? Can anyone help me?

When the error occurs, what do you want to say to the user? I assume you don’t want the bot to not respond at all. Typically, you’d let the user know there was some problem and possibly re-prompt for the requested information or take another path.

For instance, you might want to respond with an error message and exit the form.

ConversationPaused would not typically be used in this scenario unless maybe you were transferring the user to a live agent.
