Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl

[erperejildo]

What went wrong:
A problem occurred configuring project ':contacts_service'.

Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

 If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

AGP Upgrade Assistant didn't help to fix the issue since I get exactly the same error: Namespace not specified
I have also a specified namespace in my build.gradle and AndroidManifest.

contacts_service: ^0.6.3
