Problem checking config and restarting HASS

Configuration
1

Hello,

I currently have a wired problem I can not find a point to search for the root cause.

Since I upgraded to 2021.12.6, I have wired issues restarting the server from UI and also checking the config. It always tells me, that it encounters an invalid domain custom_components.nodered and is not restarting. It simply adds this new log entry (counts up the occurences):

Logger: aiohttp.server
Source: loader.py:580

    raise ValueError(f"Invalid domain {domain}")
ValueError: Invalid domain custom_components.nodered

I already updated the companion integration, all node-red palettes and also deactivated all node-red tabs. But the problem still persists. I also could not find a working solution searching through the forums and the web.

OK, found the solution… From my previos problem, a debug statement in configuration.yaml

custom_component.nodered: debug

survived and led to this error.

I found this “accidently” by grepping through the config folder of HASS on the shell. Unfortunately, the error message gives no hint, where to search, but from now on, I’ll more often use grep to nail down a problem :wink:
