Execution failed

I am trying to build an app from GitHub in Android Studio and I am getting the following error message:

Task :app:processFreeDebugGoogleServices FAILED
Parsing json file: /home/clgp/AndroidStudioProjects/scratchjr/android/ScratchJr/app/google-services.json

FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:app:processFreeDebugGoogleServices’.

No matching client found for package name ‘org.scratchjr.androidfree’

I already tried:

delete google-services.json file, signing up to firebase to create from there a new google-services.json file

updating bundle, AndroidStudio and google-services

uninstall and install the app

I would be very gratefull if somebody could give me a hitn what else I could try…
thanks.
