signInWithCredential get stuck

auth.service.ts の loginWithGoogle メソッドから開始し、指定された Angular、Firebase、Ionic、Capacitor のバージョンでネイティブパスを再現します。SocialLogin.login、GoogleAuthProvider.credential、signInWithCredential の周辺の動作を比較し、デバイスが応答しなくならないこと、および失敗時にエラーが発生することを確認します。

Version info

"@angular/core": "19.2.3"
"@angular/fire": "^19.0.0",
"firebase": "^10.14.1",
"@ionic/angular": "^8.3.4",
"@capacitor/core": "^6.1.0",

Code

import { Auth, GoogleAuthProvider, signInWithCredential, signInWithPopup, UserCredential } from '@angular/fire/auth';

private auth = inject(Auth); //* Firebase Auth instance

async loginWithGoogle(): Promise<UserCredential> {
        SummonLogger.trace('auth.service.ts', 'loginWithGoogle');
        try {
            const provider = new GoogleAuthProvider();

            if (!Capacitor.isNativePlatform()) {
                return signInWithPopup(this.auth, provider);
            } else {
                // Native auth (capacitor)
                await this.initGoogleProvider();
                await this.clearGoogleSocialLoginSession();
                const res = await SocialLogin.login({ provider: 'google', options: {} });
                this.provider = 'google';
                const googleResult = res.result as GoogleLoginResponse;
                const credential = GoogleAuthProvider.credential(googleResult.idToken);
                return await signInWithCredential(this.auth, credential);
            }
        } catch (error) {
            SummonLogger.error('auth.service.ts', 'loginWithGoogle() - error', error);
            return Promise.reject(error);
        }
    }

Issue

When the signInWithCredential method is invoked, the device becomes unresponsive, seemingly freezing in place. Despite this halt in functionality, no error messages or alerts are displayed to indicate the problem.
