Hi there, can you post your endpoints.yml please?

try to run rasa shell --endpoints endpoints.yml --debug and make sur that your rasa server run on another terminal " rasa run actions"

I restarted my editor, and it again started working without any changes, I don’t know how this occured, and this is the 3rd time I faced this issue.

That’s really strange, so it’s probably an editor problem somehow? What editor do you use?

I’m using Visual Studio Code. This same error I got earlier also.

@Mayankgbrc @erohmensing I am facing this same issue. I am following Rasa Master Class #6 and have set up and started the action server. The server is started and the action function is registered at this point the error occurs. TypeError: type object argument after ** must be a mapping, not NoneType. I am using PyCharm as my editor, if that matters. Any help / direction would be much appreciated. VN

Same problem here. But msg i’m getting is: File “c:\python37\lib\site-packages\rasa\utils\endpoints.py”, line 154, in from_dict return EndpointConfig(**data) TypeError: type object argument after ** must be a mapping, not NoneType

@Jmg007 @Mayankgbrc @erohmensing I was able to resolve this issue after further search on Stack Overflow. Issue seems to be the Sanic Package version 19.12.2 is not compatible with Rasa. I had to downgrade the Sanic from version 19.12.2 to 19.9.0. reference: Rasa Shell error following tutorial · Issue #5019 · RasaHQ/rasa · GitHub

action_endpoint: url: "http://localhost:5055/webhook" there may be some typo mistake. copy and paste the above code. @Mayankgbrc

@sushilr007 This solved my issue thanks!, apparently wrong identation can cause this error as well.
