Connection to API of Jullix EMS

I am trying to interface to my EMS as a HA newby. I put the code I found in below topic & on the Jullix support site in configuration.yaml (using the API token I created in the Jullix).

This is the result, but that does not seem right?

For future reference:
Using the developer tools, I finally found out the problem was authorization.
I have not figured out why, but the system generates 2 tokens. It is the very long one hidden behind the key icon that made things work for me.
