HA no longer includes files

I’ve had my configuration.yaml including other files with no problem until today. When I was unable to find a light for a new automation, I looked at the first part of config:

default_config:
tts:
  - platform: google_translate

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
switch: !include switches.yaml
template: !include templates.yaml
sensor: !include sensors.yaml
device_tracker: !include device_trackers.yaml
utility_meter: !include utility_meters.yaml
light: !include lights.yaml

api:
intent:

There is now a red x left of automation with the hovering error “unknown tag !<!include>”. if I comment out that line, the red x will appear on the next line and so on. where does this error come from? Has something changed?

Sounds like an issue with whatever you are using to view the files. !include has not been removed and still works.

I’m guessing you are using the File Editor Addon: https://github.com/home-assistant/addons/issues/2656

I am, yes, and I’ve read the bug report. This is one of a number of problems I’ve noticed with the latest core updates. I added several entries to my lights include file, and no entry would show when searching entities or building scripts or automations. (That’s how I got onto the file editor bug.) This morning, they just came back with no action on my part. One of my custom cards could not be found by dashboard; after two days, it came back. This morning, I got 401 errors on several pages, including file editor, backups, terminal, and AdGuard. Logging out then back in solved that one. Finally, the WeatherFlow to MQTT add-on quit connecting to the MQTT broker. That problem required a sudo reboot in terminal.

Thanks for the reply; I’ve marked it as the solution.
