Trigger the internal server error by issuing a POST command to the api/publish/:. endpoint

curl -X POST -H 'Content-Type: application/json' --data '{"Storage": "", "SourceKind": "snapshot", "Distribution": "cmake", "Sources": [{"Component": "external", "Name": "cmake_trusty-220411074201"}], "ForceOverwrite": true, "SkipContents": true, "AcquireByHash": false}' http://localhost:8080/api/publish/:.

or with python

import requests
url="http://localhost:8080/api/publish/:."
data={"Storage": "", "SourceKind": "snapshot", "Distribution": "cmake", "Sources": [{"Component": "external", "Name": "cmake_trusty-220411074201"}], "ForceOverwrite": True, "SkipContents": True, "AcquireByHash": False}
r = requests.post(url, json=data)
print(r.text)

Context

Can't use the API publish entpoint anymore after the upgrade, need to downgrade
