Action server error

Rasa Open Source
1

Hello,

I am receiving the below error while talking with the bot. This error is occuring after series of interactions with the bot. May I know, how to solve it?

ERROR: rasa.core.processor  - Encountered an exception while running action 'action_calculate_financial_knowledge_score'.
Bot will continue, but the actions events are lost.
Please check the logs of your action server for more information.

As the error recommends, please check the logs in the terminal in which you ran rasa run actions and share your action.

Hi Chris, Thanks for your reply. I ran rasa run actions and got the below.

@Priya123 Did you mentioned all the actions in domain.yml ? and what error now you seeing while running rasa shell --debug and rasa run actions --debug when talking to the bot?

Hi , running rasa run actions --port 5056 on a seperate terminal and then running rasa shell on another terminal, I get the following shown in the actions terminal

@Priya123 this issue is related to the main issue? can you please briefly explain your use case or project you doing and related files if possible? please use format for the code share.

The error is right here. self._FHS is None and you’re trying to convert it to an integer.

Basic Python will help you solve the issue:

fhs = tracker.get_slot(self._FHS)
score = 0 if fhs is None else int(fhs)
