I have the following configuration:

        stage('Snyk') {
            steps {
                snykSecurity(
                  snykInstallation: 'Snyk',
                  snykTokenId: 'SNYK_TOKEN',
                )

{

{            }

}}
        }  

The job fails with the following error:

I have tried using --debug to get more details but I have no clue. Everything seems to be working until the last part. See the attached log.

 

I think this error occurs if Jenkins is not configured to use UTF8 (-Dfile.encoding=UTF8)
