hass-magic_areas: 2.0.0: Error while setting up magic_areas platform for sensor

I have updated magic_areas to 2.0.0.

In the configuration i deleted everything related to magic_areas and only added magic_areas:

After a restart Magic Areas appears in the Integrations page with the right areas but no specific sensor has been created (Area temperature and so on, even if i edit the config through UI). Only the general area binary sensors and presence hold switches are there.

2 bad log entries are appearing:
