      Hi,

      I just upgraded Jenkins from 2.249.2 to 2.263.2, then I have some build job take a long time to start a build, regarding the log below, I foundout that this is restriction on label name.

      I set the node label in build job as below

      So I went to "Script Console" and run command: System.setProperty("hudson.model.LabelAtom.allowFolderTraversal", "true") , also tried to Reload Configuration from Disk, but the issue still occur. I'm using ECS plugin for dynamic slave.

      Something wrong or what might causing the issue?

          The problem here is that your cloud might be provisioning a node with the | character in it, which is illegal
