Hi there,

In your stories, you are using an outdated format for form events:

- story: buy_home
  steps:
  - intent: greet
  - action: utter_greet
  - intent: buy_a_home
  - action: buy_form
  - action: form{"name":"buy_form"}
  - action: form{"name":"null"}

Check out the docs for more info on how to use forms in stories in 2.0: Training Data Format

In the future, please refer to How to ask a great question when asking a question instead of just posting an error and files.
