Why is Homeassistant trying to load non-existing logbook / group / system_health /

Hi, I’m currently seeing an error that I’ve never seen before during the development of a new component.

The type of error occurs 4x: For system_health / media_source / logbook / group

Its worth to mention that the sensor part of it loads and is working fine, but why is HASS trying to load the other 4 parts?

It feels a bit silly to ask because this seams super stupid. But I’ve spend multiple hours to fix it and can’t get it to work. I’ve copied directly from my other custom_components which work all fine and even used the code from https://github.com/boralyl/github-custom-component-tutorial/blob/feature/part4/custom_components/github_custom/config_flow.py but nothing helps

The Code that’s causing the trouble is this:

Help is highly appreciated

Did you ever figure this out?

Edit: I was having the same issue with a custom component and it was because the folder name was not exactly the same as the DOMAIN. A typo I introduced while cleaning things up. Once I fixed the name, the errors went away.
