Thanks for the issue, @erohmensing will get back to you about it soon!

You may find help in the docs and the forum, too 🤗

Can you run both rasa shell and your action server in --debug mode? That might give us some more information about what's going on. Are you running rasa on a different port than usual?

What is the request you are sending via the rest API when this happens?

And the debug logs of your action server?

@erohmensing I removed the '/' after webhook in endpoints.yml
action_endpoint:
url: "http://localhost:5055/webhook"

After the change i am getting below error from actions:

@erohmensing Changed actions.py to use client.current instead of client.getcurrent. It is working fine now. Thanks
