Flutter & Shorebird build fails to upload to google Play

[AnaNedicGithub]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

The original structure of my project was this:
Folder more-app
|------ folder more_app inside
|----- lib, ios, android, codemagic.yaml etc inside

This was causing problems with the Codemagic pipeline, so I changed it: now I have onle folder more-app (the outer one), and everything else is directly inside it, like so:
Folder more-app
|------ lib, ios, android, codemagic.yaml etc inside

However, imports still look like this: import 'package:more_app/design_system/common_widgets/colors.dart'; (more _app, with the underscore).

(Yes, I regret making this module inside the folder, don't ask)

I am building app with Codemagic, shorebird is the only step I have added so far, it all goes well but I get this error at the end:

Publishing app-release.aab to Google Play
Google Play failed to upload artefacts. Package not found: com.semdatex.more_app.: {
"error": {
"code": 404,
"message": "Package not found: com.semdatex.more_app.",
"status": "NOT_FOUND"
}
}

Expected results

App bundle is uploaded to Play Store. I CAN CHANGE ANYTHING IN THE APP TO MAKE THIS HAPPEN

Actual results

Publishing app-release.aab to Google Play
Google Play failed to upload artefacts. Package not found: com.semdatex.more_app.: {
"error": {
"code": 404,
"message": "Package not found: com.semdatex.more_app.",
"status": "NOT_FOUND"
}
}
