AdMob 3.1.0 Godot 4.2.1

I don’t understand what the problem is

Godot Engine v4.2.1.stable.official
 
--- Debugging process stopped ---
  Error opening file ''.

Same, I also have this problem

I run Unbutu 22.04 and am using Godot 4.1.3.

I think the error I encountered may be related.
Everything was going fine until switching to gradle. I began getting errors:

editor/export/editor_export_platform.h:178 - Export: Building of Android project failed, check output for the error. Alternatively visit docs.godotengine.org for Android build documentation.
