Error during the logout action

[adanba]

hello

I'm trying shinyproxy 3.1.1 and when i try to disconnect by heating the sign-out button.
I get this error message in the shinyproxy logs : "Error invoking method sessionDestroyed on listener class org.springframework.security.web.session.HttpSessionEventPublisher "

When i stop manually the app with stop button on the admin ui, and i logout i didn't get this error.

Do you please have any idea why ?

Thank you
Ada
