Resolution
A fix is in the works to prevent this error from appearing, however as a temporary solution you can disable the CloudBees Fast Archiver plugin. To do that:
-
CD to $JENKINS_HOME/plugins
-
Execute the command:
touch cloudbees-jsync-archiver.jpi.disabled
-
Restart Jenkins.
This will disable the CloudBees fast archiver plugin.
