Cannot update issuelinks via api

[Jonathan Vezinat]

URL= "http://<jira url>/rest/api/2/issue/<issue key>"

JSON=

{
    "update":{
        "issuelinks":[
            {
              "add":{
                 "type": {
                    "name": "Affects",
                    "inward": "is affected by",
                    "outward": "affects"
               },
               "outwardIssue": {
                  "key": "<issue key>"
               }
            }
          }
        ]
      }
    }

The above parses fine but returns error

"Field issuelinks cannot be set.  It is not on the appropriate screen, or unknown".

I verified it is on the screen.  Am i missing something?

I was able to use above once the issue was re-opened.  It had been closed previously.
