For the above python script, dispatcher.utter_message works for action_hello_world but not for FormAction in rasa shell. Very confused about why this is happening.

Hi @ria.pinjani
I could not see your form action getting predicted.
Your stories also looks fine.
Have you included form action policy in your config ?
I could see you haven’t intended return statement line for static method in action.py. Doesn’t it throw error?
Yeah i fixed the indentation so thats not the issue.
I used the RulePolicy is my config file as mentioned here (end of page) - Policies

Since your version is 2.x, Can you update the stories to latest format as in yaml
Also share your domain file content

Hi @ria.pinjani
Domain.yml looks good.
Did you got chance to upgrade your stories to latest format stories.yml
I did - it still does not work.

Hi @ria.pinjani ,
I just noticed another error in your actions.py
Since your version is 2.x, Please make the below changes as well in your form action class.
class BalanceForm(FormAction): to class BalanceForm(Action):
def submit to def run
your stories looks good. Retrain your model & make the above updates to your actions file.
Let me know if it works.

Hi @ria.pinjani
I have fixed the code and its available here GitHub - rajaduraisingam/rasa_demo
Main issue is demo bot was developed in 1.x version but you have been trying that in 2.x . There were lot of changes happened since 1.x and hence it was throwing errors.
Have a look at the files to understand the flow.
In the above screenshot, if you enter the card number it will execute the action successfully.
However, if we don’t specify the card number, it will ask the card number. After providing the card number, it says Bye which requires small fix which you can take it forward.
