Internal Service Error when attempting to update status with JIRA API

[Kelsey Stieby]

I am attempting to update an issue status from backlog to assessment through Postman but am not having any success. I've only seen answers for how to do this through curl, which I do not have access to. Currently, I am attempting a POST with "https://<company url>/rest/api/2/issue/<issueID>/transitions" and the following body:

{

    "transition": {

        "id": "2"

    }

}

This gives me "Internal server error". I am however able to post tickets through postman so my API access shouldn't be the problem, unless it has to do with my privileges.

Any tips would be appreciated.
