2021.2.3 to 2021.3.1 Upgrade - Setup failed for automation: Invalid config


I upgraded this morning from 2021.2.3 to 2021.3.1 but it seems that my automations configuration is now invalid and not working. Did I miss a new feature/method for configuring automations that I need to fix in my “automation: !include automations.yaml” setup? All my automations had been working fine prior to the upgrade this morning

I get this when I launch hass now → (3.8) ha@mail ~/.homeassistant $ clear ; hass2021-03-05 11:03:49 ERROR (MainTh - Pastebin.com

It essentially starts with

ERROR (MainThread) [homeassistant.config] Unknown error calling automation config validator

and ends with

ERROR (MainThread) [homeassistant.setup] Setup failed for automation: Invalid config.


Not sure what’s going on here, but for the time being I have just downgraded back to 2021.2.3 with this command and all my light automation are back and working well again.

pip install --use-feature=2020-resolver --upgrade homeassistant==2021.2.3

I’m guessing there is an issue with automations in 2021.3.1 and a fix will be released in the next version.
