I want to add a JIRA label to a JIRA ticket based on the scm changes as described in
https://github.com/jenkinsci/jira-plugin/blob/master/COMPATIBILITY.md

step([$class: 'hudson.plugins.jira.JiraIssueUpdater',
                                issueSelector: [$class: 'hudson.plugins.jira.selector.DefaultIssueSelector'],
                                scm: scm,
                                labels: [ "dev","test" ]])  
The tickets gets updated, but the labels stay unchanged
00:03:23.317 [Build services and clients] [JIRA] Updating issue SERVICE-2559
 

The configured user has edit rights.

I see the following error in the jenkins logs:
