Could someone please help me, I don’t understand where I am going wrong. Thank you

@sameera looks like there was some error in your custom action. Can you post the logs of action server here? Also, can you post a small snippet of your training data to make this reproducible. Thanks

@sameera Please change your endpoints.yml file to -

action_endpoint:
  url: http://localhost:5055/webhook

It should work then.

yes, this is what i have in my endpoints.yml file.

@sameera Are you sure you have the same endpoints.yml file because the snippet you posted in the original question does not have the first line action_endpoint:

@dakshvar22 Yes I am sure.

@erohmensing Could you please look into it, I am sure that my endpoint file is correct. I don’t understand where I went wrong . I would really like to have some help on how to fix this. I have a custom actions file that would utter a template “utter_message” when “action_custom” is called. I haven’t used action_custom in my stories, I tried to run it in rasa interactive mode to check if it works and I was getting the above exception. Is it possible that not having action_custom in my stories is the problem?

I have solved the issue. Thank you

Hi @sameera , what was the problem? It would be great if you can post the solution here so that other users can benefit from it too. Thanks

@dakshvar22 As you saw in my files, I couldn’t find what the problem was. I have cross checked my files with others who had this issue and were able to solve it, my files looked fine so I figured it might be an internal linking issue. I created another environment with python==3.6 and rasa , created a project in rasa and re-ran the project in the new environment, it worked fine. Making sure all the dependencies are properly installed is important :slight_smile:

@sameera Cool. Glad you could make it work.
