cannot find assist pipeline

[south hornet]

I have updated this moring to the new core 2025.2.5. Now, when I try to access assist I get this error/message.
I have added :

Example configuration.yaml entry

assist_pipeline:

to my config.yaml file (and rebooted) to no avail. Anyone?

Please add an error, and what you added to which YAML. It's completely unclear what is the setup and problem here.

when I open assist : the assist interface gives the error: cannot find assist pipeline. I meanwhile found that this has nothing to do with the version of the installed core. A HA help page indicated to add "assist_pipeline:" to my configuration.yaml file but this doesn't change anything to the situation
