Unable to publish results. via jenkins to zephyr enterprise EC2 server

Summary:

I have zephyr running on AWS ec2 machine along with zbot. Also I have jenkins job which publish results from testng-results.xml to zephyr post build action. after build success the Automation folder doesnt create the test cases ran. Its empty. 

My setup:

- project repo is present on : home/ec2-user/preojectrepo/

- Jenkins post build action Test result file is :preojectrepo/target/surefire-reports/junitreports/*.xml

- Parser - JUnit

See attached screenshot for your reference.
