Unable to set fields in an Issue via the REST API

Question

I'm attempting to set fields on an Issue.  I've tried both the description and custom fields.

I'm doing a PUT to system.atlassian.net/rest/api/2/Issue/XXX-123

My json is simple:

{
"fields": {
"description": "This is a test"
}
}

Attempting to use version 2 I'm getting a 204 error response with nothing but headers in the response.

Attempting to use version 3 I'm getting a response of

{

"errorMessages": [],

"errors": {"description": "Operation value must be an object"}

}

Any suggestions?

I was able to get it to work using a PUT to the url

https://hostname.atlassian.net/rest/api/2/issue/JIRA-3

With a body of

{
    "id": "21960",
    "key": "JIRA-3",
    "fields": {
        "customfield_10200": "110098"
    }
}

That returns a 204 response, but it works.

Interestingly enough, as long as I have the id and key right in the body it works, and updates that id/key regardless of the issue specified in the url.  In other words I can do a PUT to issue/JIRA-123, but it will update whatever issue is specified in the body.  You do have to specify and issue in the url though.
