Expo publish:Showing below error

I am trying to build an app with expo-google-sign-in when I am publishing app using expo publish I am getting the following error.Please help me out here.

Error: Problem validating fields in app.json. See https://docs.expo.io/versions/v34.0.0/workflow/configuration/
• Field: android - should NOT have additional property ‘googleServiceFile’.
Couldn’t publish because errors were found. (See logs above.) Please fix the errors and try again.

my app.json:

“expo”: {
“name”: “googlesigninexpo”,
“slug”: “googlesignin”,
“privacy”: “public”,
“sdkVersion”: “34.0.0”,
“platforms”: [
“version”: “1.0.0”,
“orientation”: “portrait”,
“icon”: “./assets/icon.png”,
“splash”: {
“image”: “./assets/splash.png”,
“resizeMode”: “contain”,
“backgroundColor”: “#ffffff”,
“scheme”: “https”
“updates”: {
“fallbackToCacheTimeout”: 0
“assetBundlePatterns”: [
“ios”: {
“supportsTablet”: true
“android”: {
“package”: “com.test.expo.googlesignin.com”,
“googleServiceFile”: “./google-services.json”

What happens when you remove the following line?

"googleServiceFile": "./google-services.json"
