Component failing after HASS update

I've updated HASS and component can not start:

Home Assistant 2023.3.5

Now it started and fluxing sucessfully. 🤷‍♂️

How about to add else branch with some useful debug logging, so we will know more in case it happens?

That's a good idea, will leave this open as a reminder to add this when I have time - or I welcome any pull requests

It is failing again now. I've added debug output to else branch:
