For couple of days we have a problem with Jenkins nodes – after aborting any job, the script connecting us to the server on the node side gets disconnected saying “WARNING: Attempt to (de-)serialize anonymous class org.jenkinsci.plugins.envinject.EnvInjectComputerListener$2; see: https://jenkins.io/redirect/serialization-of-anonymous-classes/”.

Environment Injector Plugin
2.3.0

Jenkins Jenkins ver. 2.190.3

I checked other related issues, but none worked out.
