I try to use a user credential in declafative pipeline which I select via a credential parameter.

The parameter selection allows me to pick a credential which is scoped to my user.
How ever if I try later on to the selected credential in a withcredential block I get an error  mo such credential. If I pick a credential wit scope global the code works.

 
pipeline {
    agent none
    tools {
        jdk 'JDK 11'
         maven 'Maven 3.8.4'
        }
    options {
       buildDiscarder logRotator(
            artifactDaysToKeepStr: '',
            artifactNumToKeepStr: '3',
            daysToKeepStr: '',
            numToKeepStr: '5')
         }

    parameters {
          credentials credentialType: 'com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey',
          name: 'DEPLOY_CRED', required: true, defaultValue: '',
               description: 'The credential used on the target systems for the deployment (Username, SSH Key)'
             
         }

    stages {

        stage( 'public') {
            agent any
            steps {
                echo "Deploy monitoring on  XXX  as ${DEPLOY_CRED{color:#569cd6"}}

                withCredentials([sshUserPrivateKey(credentialsId: DEPLOY_CRED ,
                    keyFileVariable: 'KEY_PATH',
                    usernameVariable: 'REMOTE_USER' )]) {
                   
                       
                        sh 'cp -f $KEY_PATH luckilucki.txt'
                        echo "${REMOTE_USER{color:#569cd6 ${KEY_PATH{color:#569cd6}}"}}

                   }
           }
       }
   }
}
