Error in transporter to upload the pkg to app store connect

Hello, I am new for apple developer. I see the problem and I think apple show me very few error message and I do not know to start with it.

I was created my app by python and build to .app then package it to pkg by the pkgbuild.

I have problem to upload the pkg file to app store connect by transporter both CLI and GUI.

when I try to upload it by GUI, I see this message.

Cannot find the ITMSP file: (null). (11)`

and when I upload my pkg by the CLI, I found more message but still cannot start with it as well.
