Admob free with capacitor doesn't work

I’m trying to use AdMob free plugin at this version:

"cordova-admob-sdk": "^0.24.1",
 "cordova-plugin-admob-free": "^0.27.0",

But android always throw error because it seems that a package used on the plugin is no longer available: * package does not exist

This will stop the app at the very build.

There are some solutions to this?
