[JENKINS-68162] NullPointerException from withCredentials > sshUserPrivateKey

Hello!

Here is a snippet from Pipeline:

 

sshagent(["AWSServerPrivateKey-${params.URL}"]) {

 withCredentials([sshUserPrivateKey(credentialsId: "AWSServerPrivateKey-${params.URL}", usernameVariable: 'userName')]) {

  sh "cat hello.txt"

  }

 }

I get the following error
