      From a 2.138.x, install the blue ocean plugin and use a plugin allowing a null display name. Eg:

      pipeline {
    agent none
    stages {
        stage("Checkpoint") {
            steps {
                checkpoint null
            }
        }
    }
}

      Note: the null is valid here and was supported in earlier versions.

      Build will fail with a stack in the listener:
