Error while setting up vulcan platform for sensor

[Krzysiekmkg9]

Hi, I would like to use your integration but my HA gets an error when setting up Vulcan. Integration was installed by HACS. I can set up integration but after it, I don't get any entities, and in the logs, I have this information

Logger: homeassistant.components.sensor
Source: custom_components/vulcan/get_data.py:127
Integration: Sensor (documentation, issues)

This is a known issue but has already been fixed - we are currently waiting for a new version of the API to be released.
