Using plugin @havesource/cordova-plugin-push causes build failure

Hi,
I have build an Android app using plugin @havesource/cordova-plugin-push successfully in the past.
Now I’m getting a build error (not happening when I remove the plugin) talking about /com/adobe/phonegap/push code which I don’t understand where it comes from. Because this plugin should replace the phonegap push plugin.

Task :app:compileDebugKotlin FAILED

Do you have any idea what could be the problem?
Thanks,

Are the rest of your plugins up to date? And are you using the latest android engine?
