You have an authentication error. Are you sure you're using the right environment (Sandbox or Production mode)?

[Bubba8291]

I figured it out. I was logged into my main apple id in the sandbox environment. To fix that, generate a sandbox apple id in app store connect, then login to the sandbox apple id you just created by going to Settings->App Store->Sandbox Account.

The issue got resolved on its own after waiting for one day. That was some kind of weird error from apple servers. Thanks for the support.

One thing that can cause this error is having a subscription without a duration set in App Store Connect.

Its possible to go through the flow and set the price without a duration for some reason.
