How to add asset and sign aab file (Android only)

Error: File ‘BundleConfig.pb’ was not found.
When upload to Google Play

See this: Google Play Store error 403 File 'BundleConfig.pb' was not found - Questions - VoltBuilder

I discovered of my files not are in root directory.
When compact to ZIP, the program created new folder with same name of app.

Now, the signature is not valid when upload in a PlayStore
I am going to discovery why

Same error.
Signed with my android.keystore exported from Kodular
What to do?

Signed with jarsigner but, same error in upload to Play Store: Signature invalid

This, is important?
Warning of jarsigner:

The signer’s certificate is self-signed.

Now go to base>assets>here paste your file

Which File you Upload ???
