Not able to upload cucumber json file to Zephyr Scale

Hello Team,

I am using the postman with form data to upload the cucumber json in a zip file format to ZephyrScale that we have installed in our companies JIRA data center edition.

API Endpoint : http://jira.telesat.com/rest/atm/1.0/automation/execution/cucumber/LSTI

Method : POST

Form data : file = output_results.zip

Authentication = Basic with user name and password

I am getting 500 error back.

Feature file was exported directly from zephyr and tags are proper as well.

Can you please help.
