Hi!
I was reading this article https://developer.samsung.com/sdp/blog/en-us/2022/06/02/app-management-using-the-galaxy-store-developer-api-and-python#jsblog-create-session-id 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
