Rasa Open Source Feedback on Rasa Open Source

Hello,

From requirement side :- When user want to place an order, user will be shown two options to select as given below :-

veg_non_veg

Let’s say user selected Vegetarian as option, again from the veg menu options will be listed for user like below :-

veg_options

Finally user selected something from menu and then using custom action we are displaying it back to user like below :-

veg_options_done

If I look at from functionality point of view, my chatbot is working as expected, but on CMD I can see some error, can someone please help me to fix these errors and here is the screenshots of errors :-

I have mention my domain.yml, stories.yml, rules.yml, nlu.yml and custom action action_show_order_items.
