Invalid App Bundle : 'BundleConfig.pb' file missing

[crat1985]

Here is the complete error from bundletool build-apks :

[BT:1.15.6] Error: The archive doesn't seem to be an App Bundle, it is missing required file 'BundleConfig.pb'.
com.android.tools.build.bundletool.model.exceptions.InvalidBundleException: The archive doesn't seem to be an App Bundle, it is missing required file 'BundleConfig.pb'.

It happens also when I try to upload it on Google Play.
It happens if the app is signed and if it isn't.

I created a repo if you want the files : https://github.com/RIC217/test-winit-android
