Description

Hey, can someone help me out? I try to use the api to create a release. I get no reply, but the server log shows me an internal server error.

curl -X POST "https://SERVER/api/v1/repos/USER/REPO/releases" -H "Content-Type: application/json"  -H "Authorization: token TOKEN" -d "{ \"body\": \"test\", \"draft\": false, \"name\": \"test\", \"prerelease\" : false, \"tag_name\": \"v2.1.1\", \"target_commitish\": \"f34f281e6045a20cd79f85d31a585bd40cbe473d\"}"

Obfuscated SERVER, USER, REPO, TOKEN.

This is the log:
