Error during setup of component circadian_lighting

[TIMSCHMITZ]

After adding circadian_lighting to my configuration.yaml

  - platform: circadian_lighting
    lights_xy:
    - light.0x680ae2fffe161079_light

i recive the error in my main log:

I had the same problem after installing it via HACS. I needed to add empty circadian_lighting: into configuration.yaml and then it worked.

<..>
circadian_lighting:

switch:
  - platform: circadian_lighting
    lights_xy:
    - light.0x680ae2fffe161079_light

I've hit the same error on 2023.12.1. This hack helped but I wouldn't consider that as a fix...;)
