Error: Failed to initialize Google Cloud Firestore client with the available credentials. Must initialize the SDK with a certificate credential or application default credentials to use Cloud Firestore API

Using the new version 8.9.1 of firebase-admin, firebase-functions deployments using NodeJS 10 with the Firebase CLI fail. Reverting firebase-admin to version 8.9.0 resolves the issue.

Here is the command used to deploy functions:

$ firebase deploy --only functions

The line 10 from account-active.js is const firestoreDatabase = admin.firestore();.

Firebase admin initialization is made as follows:

import {FirebaseAdminHelper} from '../helpers/firebase-admin-helper';
const admin = FirebaseAdminHelper.initializeApp();
const auth = admin.auth();
const config = functions.config();
const firestoreDatabase = admin.firestore();

where FirebaseAdminHelper is defined as follows:

import * as admin from 'firebase-admin';

export class FirebaseAdminHelper {

    static initializeApp(): admin.app.App {
        try {
            return admin.initializeApp();
        } catch (error) {
            // Ignore "already initialized" errors.
            // This case should only happen locally while deploying, not on real environments.
            return admin.app();
        }
    }

}

temp fix:

npm i firebase-admin@8.9.0

issue only seems to affect 8.9.1

Same problem here using :

admin.initializeApp({ credential: admin.credential.applicationDefault() });

Downgrading using yarn add firebase-admin@8.9.0 seems to get it working again.

Thanks @darinw
