Can't update jira issue with REST API

[red888]

I'm trying to do this with powershell, but I'm getting 400 errors:

$RESTURL = 'https://mycomp.atlassian.net/rest/api/latest/issue/PROJ-61'
$body = '{"fields":{"assignee":{"name":"me"}}}'
$restcreds = [System.Convert]::ToBase64String(
[System.Text.Encoding]::ASCII.GetBytes(('me' + ":" + 'mypass123'))
)
$httpheader = @{Authorization = "Basic $restcreds"}
$restParameters = @{
Uri = $RESTURL;
ContentType = "application/json";
Method = "PUT";
Headers = $httpheader;
Body = $body;
}
Invoke-RestMethod @restParameters

If I remove "body" from the request and change it to a get I get back data successfully. It seems I just get modify the ticket

Make sure you have assignee field on the edit screen of the issue.

Make sure your JSON is per the API specs

From the docs - "The simple way to update an issue is to do a GET, update the values inside "fields", and then PUT back."

Thus do a get request and then then a put request with the same json data and just modify the "assignee" filed to a proper user ID , "me" isn't a userId it seems which you are doing right now.
