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: (base) C:\Users\g.a.mahalingam\Documents\weather>rasa run actions --debug 2019-08-09 11:27:26 INFO rasa_sdk.endpoint - Starting action endpoint server... c:\programdata\anaconda3\lib\site-packages\rasa_core_sdk__init__.py:12: UserWarning: The 'rasa_core_sdk' package has been renamed.

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