Need help with slot filling using buttons

Rasa Open Source
1

I am using rasa 3.1

This is domain file code

  time_slot:
    type: text
    influence_conversation: false
    mappings:
      - type: from_entity
        entity: time_slot

  utter_ask_time_slot:
    - text: "Which time slot would you prefer?"
      buttons:
      - title: "9 AM to 10 AM"
        payload: '/choose_time{"time_slot":"9-10"}'
      - title: "2 PM to 3 PM"
        payload: '/choose_time{"time_slot":"2-3"}'
      - title: "4 PM to 5 PM"
        payload: '/choose_time{"time_slot":"4-5"}'

This is the nlu file

- intent: choose_time
  examples: |
    - I prefer [9-10](time_slot) am
    - [2-3](time_slot) pm works for me
    - Can I get [4-5](time_slot)? pm

I am getting this error 2024-02-29 17:58:58 ERROR rasa.core.processor - Encountered an exception while running action ‘utter_ask_time_slot’.Bot will continue, but the actions events are lost. Please check the logs of your action server for more information.

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

This is what chatgpt suggests about the error The error you’re encountering, specifically KeyError: '"time_slot":"9-10"' during the processing of utter_ask_time_slot , indicates an issue with how string interpolation is being handled within the Rasa NLG (Natural Language Generation) system. The traceback suggests that there’s an attempt to format a string with named placeholders that are not present, likely due to the way the payload in the button is structured.

Pls help me on this kindly
