I run rasa with pycharm.
Can you tell me the result of debug mode briefly?
And how can i run action server?
I started to use rasa recently so please understand
Thanks
How do you run your bot in pycharm? Do you use rasa/rasa/__main__.py as script path? If so you can simply add --debug to the parameters to run Rasa in debug mode. Take a look at the Command Line Interface for all available options.
In order to run the knowledge base action you have to start an action server, see Rasa SDK. The knowledge base action is a custom action, Rasa cannot execute it unless you start the action server.
The action itself looks fine. Seems like you did not anything from the default action. Is that correct?
I run rasa using rasa nlu and rasa core seperately . I knew my way was old version.
I saw rasa tutorial and trying to run rasa with terminal. But rasa run action command returns this
OSError: [Errno 98] error while attempting to bind on address ('0.0.0.0', 5055): address already in use
Anyway I think I have to learn more about how to use rasa commands and action server first.
And then use the knowledge base action. I really appreciate your comments.

The error tells you that there is already a server running on port 5055. What commands are you executing?
I thought custom action needs def run part, so I defined my action like that(default).
Yes, but your custom actions inherits from ActionQueryKnowledgeBase which already implements the run method. So, if you don’t want to modify it, you don’t have to define it in your custom action.
Thanks
