Service account with google cloud not working

I am trying to communicate with google cloud and the service APIs by creating a service account from my local machine. i am on Mac OS

I am following this article

https://cloud.google.com/docs/authentication/production

I have set the "GOOGLE_APPLICATION_CREDENTIALS" env variable in my local session of terminal.

It points to the key file of the service account created through google cloud console.

But running the node js program below gives me the error

    // Imports the Google Cloud client library.
const {Storage} = require('@google-cloud/storage');

// Instantiates a client. If you don't specify credentials when constructing
// the client, the client library will look for credentials in the
// environment.
const storage = new Storage();

try {
  // Makes an authenticated API request.
  const results = await storage.getBuckets();

  const [buckets] = results;

  console.log('Buckets:');
  buckets.forEach(bucket => {
    console.log(bucket.name);
  });
} catch (err) {
  console.error('ERROR:', err);
}

Error is

    const results = await storage.getBuckets();
                        ^^^^^^^

SyntaxError: Unexpected identifier

Seems to be an error while reading the credentials as the storage object could not be instantiated.

You have to use await in async function. Assuming that you created a service account with the necessary permissions (Storage Admin), and exported the env variable GOOGLE_APPLICATION_CREDENTIALS then this is the code that worked for me:

   'use strict';

const authCloudImplicit = async () => {
  // [START auth_cloud_implicit]
  // Imports the Google Cloud client library.
  const {Storage} = require('@google-cloud/storage');

  // Instantiates a client. If you don't specify credentials when constructing
  // the client, the client library will look for credentials in the
  // environment.
  const storage = new Storage();

  try {
    // Makes an authenticated API request.
    const results = await storage.getBuckets();

    const [buckets] = results;

    console.log('Buckets:');
    buckets.forEach(bucket => {
      console.log(bucket.name);
    });
  } catch (err) {
    console.error('ERROR:', err);
  }
  // [END auth_cloud_implicit]
};

const a = authCloudImplicit();
