Task :app:processDebugGoogleServices FAILED

[Taxom]

Hello.
I am a newcomer in compilation of applications.
Installed:

Android Studio Giraffe | 2022.3.1
Build #AI-223.8836.35.2231.10406996, Built on June 29, 2023
Runtime Version: 17.0.6+0-B2043.56-10027231 AMD64
VM: Openjdk 64-bit server vm by jetbrains s.R.O.
Windows 10 10.0
GC: G1 Young Generation, G1 Old Generation
Memory: 1280m
Cores: 12
Registry:
external.system.auto.import.disabled = true
IDE.TEXT.EDITOR.WITH.PreVIEW.SHOW.Floating.TOOLBAR = false

When trying to compile this, I get a mistake:

Task :app:processDebugGoogleServices FAILED
Execution failed for task ':app:processDebugGoogleServices'.
File google-services.json is missing. The Google Services Plugin cannot function without it.
Searched Location:
G:\android_git\OpenCPN-Android-Android_5.8.4-101-\app\src\debug\google-services.json
G:\android_git\OpenCPN-Android-Android_5.8.4-101-\app\src\google-services.json
G:\android_git\OpenCPN-Android-Android_5.8.4-101-\app\google-services.json

What am I doing wrong?
