Login on IOS with ionic and firebase fails with Plugin.swift:65: Fatal error: Unexpectedly found nil while implicitly unwrapping

[moblizeit]

I have followed the instructions and still getting this error when i try to deploy on device.

my capacitor.config.ts has the following

plugins: { GoogleAuth: { scopes: ['profile', 'email'], serverClientId: 'xxxx.apps.googleusercontent.com', forceCodeForRefreshToken: true, }, }

i have GoogleService-info.plist added in ios/App/App

and my code to sign in looks like below

` import { Auth, GoogleAuthProvider, signInWithPopup } from '@angular/fire/auth'; import { signInWithCredential } from 'firebase/auth'; import { GoogleAuth } from '@codetrix-studio/capacitor-google-auth';

@Injectable({ providedIn: 'root' }) export class AuthenticationService {

constructor( @Optional() private auth: Auth) {

}

async googleSignIn() { let googleUser = await GoogleAuth.signIn(); const credential = GoogleAuthProvider.credential(googleUser.authentication.idToken); return signInWithCredential(this.auth, credential); } `

And this fails in xcode on clicking the sign in as below

CodetrixStudioCapacitorGoogleAuth/Plugin.swift:65: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value 2023-07-24 04:52:58.723606+0530 App[2308:582000] CodetrixStudioCapacitorGoogleAuth/Plugin.swift:65: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value

if it helps below is my package.json

I was receiving this error, when I did not correctly name the Plist file downloaded from google.

[acidumirae]

@nick-barth GoogleService-Info.plist is optional according to the README.md - I do not have it and have the same crash in this plugin.

[acidumirae]

In my case the error was caused by "serverClientId" at capacitor.config.json When it should be "clientId"

[moblizeit]

for me the GoogleService-Info.plist was not copied to the ios folder in xcode. closing it
