Jira Server platform REST API

Hi Experts,

I’ve got error message :
{“reporter”:“Field ‘reporter’ cannot be set. It is not on the appropriate screen, or unknown.”,“status”:“Field ‘status’ cannot be set. It is not on the appropriate screen, or unknown.”}}
when I call the CreateIssue API.

It seems that I can’t set ‘reporter’ and ‘status’ .
I’m sure I using Admin account, and I see those two columns on page.
Is there any setting that has to be sets up?

Can you attach the request JSON, please?

‘Reporter’ can not be set in Jira Cloud since Jira uses the field name in the atlassian-connect.json to determine the reporter name.
