I apologize if this is documented somewhere but I could not find it. What seems to have been fixed in 2025.2 is just now happening to me.
Error on the simplest of new automations.
“Your new automation has saved, but waiting for it to setup has timed out. This could be due to errors parsing your configuration.yaml, please check the configuration in developer tools. Your automation will not be visible until this is corrected, and automations are reloaded. Changes to area, category, or labels were not saved and must be reapplied.”
default_config:
frontend:
themes: !include_dir_merge_named themes
extra_module_url:
