Can't submit app with Content Publish API

I was reading this article and the last two - Modify app data and Submit app seems not to be working. I fixed the problem with modifying app data by replacing header field ‘Accept’ with ‘Content-Type’ field.

But submitting app is not working. I do everything exactly by the manual and even tried doing it with curl Content Publish API | Samsung Developers

The response is

{"from":"seller","body":{"ctntId":"<my-client-id>","contentStatus":null,"httpStatus":"BAD_REQUEST","errorCode":"6002","errorMsg":"Check validation(Essential Input)"},"message":"Request failed with status code 400"}

Everything else is working which proves my access token, service-account-id and content id are right

Fixed with adding field “publicationType”:“03” to payload of the modify app data step
