Using a declarative Jenkinsfile with a script embedded in it, I am trying to unstash a file from a slave node to another slave node. However, this code:

    stage('Unstash key generation script and assign a cron to is if they dont exist'){



        agent{

            label 'generate'

        }



        steps {

            script{



                def cronExists = fileExists 'myCron'



                if(!cronExists){

                    node('generate'){

                        node('build'){

                            stash includes: '/var/jenkins/workspace/q-go-pipeline/generateSigningKey.sh', name: 'generate-key'

                        }   

                        unstash 'generate-key'

                    }



                    sh 'echo "*/5 * * * * /var/jenkins/workspace/q-go-pipeline/generateSigningKey.sh" >> myCron'

                    sh 'crontab myCron'

                }

            }

        }       

    }

Is generating a stash error ERROR: No files included in stash. But when I go on the build node and cat the file, it exists.

The general gist is that if a file cronExists does not exist on the slave, then grab a stashed file from the build node, put it onto the generate node, then run that script every 5 minutes. If the file does exist, it will skil this step and just sign a file with a another script.
