Hi @Arghya999. It’s not your domain.yml that’s getting errored, it’s your endpoint.yml (you’ll notice in the Traceback that the issue is happening in read_endpoint_config). If you put your endpoint.yml through yamllint, you get the same error. The issue seems to be not having spaces after your colons for username and password. This fix should work:

Content of endpoint.yml

action_endpoint:
url: "http://localhost:5055/webhook"
tracker_store:
store_type: mongod
url: mongodb://mongo:27017
db: rasa
username: none
password: none

P.S. For future reference, you can

preserve 
    indentation 

in your code with three ticks (```) above and below the code. This is helpful for legibility of stack traces as well as things like domain files 🙂
