[mdiqbalhassan]

When ever I curl JIRA Datacenter  users API returns internal server error

Command : curl -u username:password https://jira.abc.com/rest/api/2/issue/TN-123

output: getting {"errorMessages":["Internal server error"],"errors":{}}

its occur for only one project . otherwise its working fine for others  project

Dear @mdiqbalhassan ,

I suggest to do the following:

1. figuring out, what's the difference between the one project and the others
2. use diffrent credentials
3. use Postman or another REST API browser extenstion to reproduce the behavior

So long

Thomas
