XrayImportFeatureBuilder Jenkins integration makes empty .zip after finding feature files

Question

I have XRAY integrated with Jenkins and our Jira instance following the documentation here I have no issues with XrayImportBuilder to import execution results or XrayExportBuilder to export scenarios from JIRA to run on jenkins.

When i use XrayImportFeatureBuilder to import scenarios into Jira, my .zip file remains empty and the import fails.

stage('Xray import feature files to Jira') {
            steps {
                step([$class        : 'XrayImportFeatureBuilder',
                      serverInstance: automatedTestConstants.SERVER_INSTANCE,
                      projectKey    : 'TEST',
                      folderPath    : "${env.WORKSPACE}/${JOB_BASE_NAME}/src/test/resources/features"
                ])
            }
        }

the Jenkins trace shows

File: d:/JenkinsBuild/workspace/xxx/src/test/resources/features
File found: d:\JenkinsBuild\workspace\xxx\src\test\resources\features\xxx.feature
File found: d:\JenkinsBuild\workspace\xxx\src\test\resources\features\yyy.feature

If i manually use the api to import a zip containing the same features, i get no errors.
