I have deployed the following firebase function: 

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

admin.initializeApp();

// other functions

exports.createProfileDocument = functions.auth.user().onCreate(async user => {
    await admin.firestore().collection('profiles').doc(user.uid).set({
        userName: user.displayName
    })
});

This was working but recently stopped, when a new user account was created the function would simply not fire (nothing in the logs, no errors, no activity, etc.). I updated my dependencies to the following:

  "dependencies": {
    "firebase-admin": "^8.0.0",
    "firebase-functions": "^2.3.1",
    "firebase-tools": "^6.11.0"
  },

The function is now firing when I would expect but fails with the following error: 

/user_code/node_modules/firebase-admin/node_modules/@google-cloud/firestore/build/src/index.js:740
    async initializeIfNeeded() {
          ^^^^^^^^^^^^^^^^^^

Any ideas?

It looks as though this was failing due to the async keyword before initializeIfNeeded() as this is not available in node 6. I was able to resolve the issue by adding 

"engines": { "node": "8" }

To my package.json

You need to update your node to version 8.x, which allows async hooks.
