Description

I've tried using PATCH to
https://gitea.local/api/v1/repos/USER/REPO/issues/1

with post fields:

• {"labels":[73]}
• {"labels":73}
• {"labels":['name']}
• {"labels":'name'}
• {"label":[73]}
• {"label":73}
• {"label":['name']}
• {"label":'name'}

The issue is returned but no label has been added to it, much like #5435 but that is for a PR not Issue.

Label 73:"name" does exist on the repo. I can manually add it.

Am I using wrong post data? Wasn't sure to use name or id or array? Should this work? Thanks.

Turns out there is another API endpoint specifically for labels. Had success with:
POST /repos/{owner}/{repo}/issues/{index}/labels
with post fields {"labels": [73]}
