Firebase Cloud Functions: app/invalid-credential failed to fetch a valid Google OAuth2 access token Firebase Admin SDK

[REQUIRED] Environment info

firebase-tools: 7.5.0

Platform: macOS

[REQUIRED] Test case

[REQUIRED] Steps to reproduce

I am new to Cloud Functions. I followed the docs, and the new initialization syntax for firebase-admin, but I am getting an auth error when running the function on the server and on a localhost.

https://firebase.google.com/docs/functions/beta-v1-diff#new_initialization_syntax_for_firebase-admin

@firebase/database: FIREBASE WARNING: {"code":"app/invalid-credential","message":"Credential implementation provided to initializeApp() via the \"credential\" property failed to fetch a valid Google OAuth2 access token with the following error: \"Error fetching access token: Error while making request: getaddrinfo ENOTFOUND metadata.google.internal. Error code: ENOTFOUND\"."}

I tried instantiating the sdk with a serviceAccountKey, same issue. https://firebase.google.com/docs/admin/setup#initialize_the_sdk

The function is being triggered on localhost and on the server, and error is being thrown once the call to the database is being made at gettingUser()

When running locally after building:

$ firebase experimental:functions:shell
firebase > const data = {some_article...}
firebase > addingNewArticle(data)
'Successfully invoked function.'
firebase > >  New article created articleId1

DEBUG: @firebase/database: FIREBASE WARNING: {"code":"app/invalid-credential","message":"Credential implementation provided to initializeApp() via the \"credential\" property failed to fetch a valid Google OAuth2 access token with the following error: \"Error fetching access token: Error while making request: getaddrinfo ENOTFOUND metadata.google.internal. Error code: ENOTFOUND\"."}

/index.ts

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';

admin.initializeApp();

export const addingNewArticle = functions.database
.ref('/articles/{articleId}')
.onCreate(async (snapshot, context) => {
  const articleId = context.params.articleId

  const result = await gettingUser();
  console.log(`From onCreate ${result}`);


  console.log(`New article created ${articleId}`)

  const articleVal = snapshot.val()
  const name = articleVal.name
  const addedById = articleVal.addedById

  console.log(`${name} was added by: ${addedById}`);
  console.log(`burgersVal: ${articleVal}`);
  console.log(`snapshot: ${snapshot}`);


  return Promise.all([])
})


export async function gettingUser() {
    const result = await admin.database().ref(`users/fnkjasdfadsfna.d`).once('value');
    console.log(`Looging new user ${result.val()}`);
    return result.val()
}

To anyone experiencing this issue:

• If you’re seeing it in the emulator you can fix it by either setting GOOGLE_APPLICATION_CREDENTIALS to a service account or running gcloud auth application-default login on your machine.
• If you’re seeing this in production then it may be that someone has modified the service accounts attached to your project that a Functions service experiencing a temporary hiccup. If the problem persists, please reach out to support.

After upgrading to Mac OS Catalina I encountered this issue. What resolved it for me was running the following commands:

• firebase login
• export GOOGLE_APPLICATION_CREDENTIALS="<PATH_TO_YOUR_SERVICE_ACCOUNT_KEY_JSON>"
