Hi Got it. I was forgot to add enable api.

Thank you :slight_smile:

great to here that, you have to start endpoints and the start run rasa core. be carefull will with path of actions

I am having: Traceback (most recent call last): File “/Users/brijeshlakkad/Library/Python/2.7/lib/python/site-packages/rasa_core/processor.py”, line 323, in _run_action events = action.run(dispatcher, tracker, self.domain) File “/Users/brijeshlakkad/Library/Python/2.7/lib/python/site-packages/rasa_core/actions/action.py”, line 323, in run raise Exception(“Failed to execute custom action.”) Exception: Failed to execute custom action. - - [2018-10-21 20:32:30] “POST /webhooks/rest/webhook?stream=true&token= HTTP/1.1” 200 212 0.216400

Can anyone please help me? thank you

@Brijeshlakkad you must have yourr actions.py and then run the two lines on different command lines.

1-python -m rasa_core_sdk.endpoint --actions actions

2-python -m rasa_core.run -d models/dialogue -u models/nlu --endpoints endpoints.yml````

Thanks. It worked!

yes of corse

Hi @azizullah2017

I’m using RASA X and facing the same issue. I’m executing the following commands

  1. rasa run actions
  2. rasa shell --debug

Following is my error

Could you please help me solve my error?

Thanks in advance.

you forget to add the name of your actions in you domain file and you must add it also stories can just publish to have full idea .

Thanks for your response. @hajoura I have it both in the actions in the domain file and the stories file.



  • action_send_apt_msg


  • sendaptmsg
    • action_send_apt_msg

I have this in my actions.py:

def name(self): return ‘send_apt_msg’

It works when I return ‘action_send_apt_msg’ instead of ‘send_apt_msg’ in the name function.


Hey @Mounika can you tell me how did you solve this issue?
