I installed HA core 2026.9.2 today and I tried to migrate my views using Sections.

my configuration.yaml file (extract):

my conf_lovelace.yaml file (extract)
resource_mode: yaml

When I reload the view (with three points + Actualiser/reload) et shift reload of the navigator I have the following:
Have you an idea ? I’m lost 
Many thanks
