Firebase functions cannot deploy : SyntaxError: Unexpected token function

I am trying to deploy a function to firebase and I get an error during deployment

Error: Functions did not deploy properly.

Could it be linked with the async function ?

Actual behavior Functions get deployed with errors, the cli shows me the following message:

================ console log ================

> eslint .
✔  functions: Finished running predeploy script.
i  functions: ensuring necessary APIs are enabled...
✔  functions: all necessary APIs are enabled
i  functions: preparing functions directory for uploading...
i  functions: packaged functions (56.39 KB) for uploading
✔  functions: functions folder uploaded successfully
i  functions: updating function sendContactEmailOAuth...
⚠  functions[sendContactEmailOAuth]: Deployment error.
Function load error: Code in file index.js can't be loaded.
Is there a syntax error in your code?

       ^^^^^^^^

================ functions index.js file ================

const functions = require('firebase-functions');


const admin = require('firebase-admin');
   admin.initializeApp();

   const { JWT } = require('google-auth-library/build/src/index');

   exports.sendContactEmailOAuth = functions.https.onRequest((req, res) => {
 const sender_msg = 'just a test'
 const email = '[email protected]'

 async function getJwt() {
   const client = new JWT(
     functions.config().service_key.client_email,
     null,
     functions.config().service_key.private_key,
     ['https://www.googleapis.com/auth/cloud-platform', 'https://mail.google.com'],
   );
     await client.authorize();
      const url = `https://www.googleapis.com/dns/v1/projects/${functions.config().service_key.project_id}`;
   const res = await client.request({ url });
   console.log(res.data);
 }

getJwt();

 });

If you are still having the issue on a recent version (such as node 12), use the ecmaVersion parser option in your .eslintrc.js file.

Here's a sample:

module.exports = {
  root: true,
  env: {
    es6: true,
    node: true,
  },
  parserOptions: {
    ecmaVersion: 8,
  },
  extends: [
    "eslint:recommended",
    "google",
  ],
  rules: {
    quotes: ["error", "double"],
  },
};

h/t to Dean for the original suggestion.

As of September 2019:

  1. Update firebase-admin : npm install --save firebase-admin
  2. Update firebase-functions : npm install --save firebase-functions
  3. Add "engines": { "node": "10" } to your /functions/package.json
...
"dependencies": {
    "firebase-admin": "^8.5.0",
    "firebase-functions": "^3.2.0"
  },
  "devDependencies": {
    "tslint": "~5.19.0",
    "typescript": "~3.6.2"
  },
  "engines": {
    "node": "10"
  }
...

As of August 2018:

Cloud Functions now support Node 8 (8.11.1). Check out this blog post.

Upgrade to Node 8

As suggested in this blog post, follow these steps to upgrade to Node 8:

  1. Upgrade your firebase-functions version via npm install --save firebase-functions@latest
  2. Upgrade firebase-tools via npm update -g firebase-tools
  3. Add "engines": { "node": "8" } to your /functions/package.json
