Ideally, you'd ensure that /run/user/$(id -u) is created during the
session launch within the docker container, so that it's present from
the beginning.

If you already have an agent running from before /run/user/$(id -u)
exists, you can kill it with a SIGTERM.  A new agent will be launched
appropriately using /run/user/$(id -u) automatically when it is needed.

all the best,
