You're building remotely on EAS, and your Google services file (./android/app/google-services.json) will not exist, since the android and ios folders are ignored and generated when building. You should use EAS credentials to manage the Google services file (https://docs.expo.dev/eas/environment-variables/#how-to-upload-a-secret-file-and-use-it-in-my-app-config). There are also a few recommendations in this issue: https://github.com/expo/eas-cli/issues/228
