Can't upload junit xml file to JIRA Hosted Server using Zephyr Scale Plugin for Jenkins

Question

I am trying to send JUnittest xml files from test pipelines in Jenkins, to [Zephyr Scale Plugin][1] on Jira Server. I have configured Jenkins correctly with the connection information and tested the connection.

In Post actions I have used the following configurations to publish the XML result:

publishTestResults serverAddress: 'https://jira.me.local/',
projectKey: 'GW',
format: 'JUnit XML Result File',
filePath: 'junitresult.xml',
autoCreateTestCases: false

I am getting the following error:

[Zephyr Scale] [INFO] Publishing test results...
[Zephyr Scale] [ERROR] There was an error while publishing test results to Zephyr Scale and they were not sent. Error details: 
[Pipeline] }
[Pipeline] // dir
[Pipeline] }
[Pipeline] // script

I tried converting the XML file to json and used the custom format but it gave me

{"errorMessages": ["Invalid Custom Format JSON file"]}

Anyone has idea?
