FileOnMasterPrivateKeySource not serializable

XMLWordPrintable

      We are seeing sporadic failures in our pipeline which is using ssh credentials for the git and sshagent steps.

      Our pipeline is along those lines:

      node {
          git credentialsId: '...', url: '...'
          sshagent (credentials: ['...']) {
              sh '...'
          }    
      }

      I believe this occurs on the git step but I can't be totally sure this is the case as the exception is always printed out at the bottom of the console log.

      Below is the exception we see on the console when the job ends. Any help to track down this issue would be greatly appreciated.

      an exception which occurred:
