OK, thanks. Any other tips about how I can debug this further?
What I am saying here is that this won't work. You are going to have
to implement this using golang (or python?). Exec requires a special
connection referred to as "upgraded" which I don't believe can be done
with the varlink clients.
These entries in the podman syslog (actually journal, but still)
look
suspicious:

My wild guess is that the client somehow exits before the podman on
the
other side of the varlink could reply.
Thanks,
