UnhandledPromiseRejectionWarning: NoSuchSessionError

App.js

const webdriver = require('selenium-webdriver'),
By = webdriver.By,
until = webdriver.until;

var driver = new webdriver.Builder().forBrowser('chrome').build();
driver.get('www.google.com');

driver.sleep(10000);
driver.quit();


When I try to run my app.js the following error appears:

$ node app.js
