Jenkins - Delete old builds script

Realice un job para eliminar los builds y mantener solo los 10 últimos pero se está comportando inestable:

Me marca el error Ignoring exception java.util.NoSuchElementException
Esto siempre pasa al intentar eliminar el último build. Si truena elimina el build antepenúltimo

Que estoy haciendo mal?

#!groovy

node {
def max_builds = 10 // max builds to keep

try {

    stage('Eliminar Builds antiguos') {
        
        getJobs().each { job ->
            try {
                def recent = job.builds.limit(max_builds)

                if (job.fullName == 'bfs-desarrollo-pipelines/pipeline-angular-test-app/master') {
                    job.builds.each { build ->
                        if (!recent.contains(build) && !build.isBuilding()) {
                            println "> > > Deleting: " + build
                            build.delete()
                            println ""
                        }
                    }
                }
            } catch(Exception ex) {
                println ' Ignoring exception ' + ex
            }
        }
        
    }

    currentBuild.result = 'SUCCESS'

} catch(e) {
    currentBuild.result = 'FAILURE'
    throw e
}

}

def getJobs() {
return Jenkins.instance.getAllItems(hudson.model.Job.class)
}

¡Hola!

Could you please provide the error console?

Sure

Thanks for you advance.
