I cannot export the test run on Jenkins with a file with xml extension

Question

(https://i.stack.imgur.com/Y9Ls3.png) I did a test run with newman on jenkins. It ran the tests and submitted the report no problem. but when I want to export and save to newman folder it gives this error. How can I solve this problem?

I downloaded reporter, junit to my computer and created newman folder but the problem is not solved.
