lowercased true/false is interpreted as a variable name in Python. to use a boolean, use True and False

side note: In rasa_sdk 1.6.1 utter_custom_json is deprecated; you should use utter_message(json_message=<message dict>) instead.

I changed boolean forrmat. Not working in rasa 2.8.14. I need help, only works with generic template,
