0.97.1 and 0.97.2 configuration check problem

on 0.97.1 and 0.97.2 [I’m using hassio on rpi3] when clicking the “check configuration” button - there is the spinning circle animation and that’s it. it never ends, configuration never checks. while looked into log file, I’ve found this:

TypeError: argument of type 'NoneType' is not iterable

I know that configuration is valid [I didn’t entered any “breaking change”, just added one light]. to troubleshoot I even tried different SD card, different power source - with no luck.

is it something bigger or it’s just on my side and I need to investigate my hardware/config further [even if it’s untouched]?

I’m having the same issue

even if those issues are not cool, that makes me a little bit happier to know I am not the only one. seriously, I was out of ideas blaming my hardware for it. right now I’m even afraid to reboot my hassio rpi3 while not knowing what’s up. I’m already done with losing few hours for multiple card flashing/config restoring action…

keep my fingers crossed it would be solved soon
