It tells you exactly where to look but you’re focusing on the 99 to 100 change.
You have an automation that’s missing a trigger. This error is occuring in the automation section at line 519 in your configuration.
Just because something doesn’t work in a new version does not mean that your configuration was correct. They continually make configuration validation changes every version. It’s very possible that it’s now catching an error in your configuration.
Thanks @petro. line 519 is the !include lines. I’ll start digging thru the automations searching for missing triggers, I got ~60 automations to look thru then.
Specifically look for spacing issues around your ‘trigger’ attribute field.
I.e:
look for:
trigger:
somefield:
Second thing, if the error occurs at 519, and line 519 is automation: !include automations.yaml, then your error is in autmoations.yaml.
Or vise versa: if the error occurs at 519, and line 519 is automation old: !include_dir_merge_list automation/, then your error is in the automation/ directory.
