OKTA API - TypeError: fs.existsSync is not a function

Question

I’m following the OKTA API instructions from this link using the code below. However, I’m getting error

TypeError: fs.existsSync is not a function

How to fix this issue? I'm using nodejs v12. wondering if there are updated instructions.

const okta = require('@okta/okta-sdk-nodejs');
const client = new okta.Client({
  orgUrl: 'https://dev-1234.oktapreview.com/',
  token: 'xYzabc'    // Obtained from Developer Dashboard
});

This is the complete error log

The code above is supposed to be used at the server side. It was place wrongly in the client side which cause errors.
