Example code does not work

[aemadrid]

When I try the example code from Basic Usage I get an error:

# web_driver_test.rb
require 'async/webdriver'

Async do
  bridge = Async::WebDriver::Bridge::Safari.start
  client = Async::WebDriver::Client.open(bridge.endpoint)

  session = client.session(bridge.default_capabilities)
  # Set the implicit wait timeout to 10 seconds since we are dealing with the real internet (which can be slow):
  session.implicit_wait_timeout = 10_000

  session.visit('https://google.com')

  session.fill_in('q', 'async-webdriver')
  session.click_button("I'm Feeling Lucky")

  puts session.document_title
ensure
  session&.close
  client&.close
  bridge&.close
end

Console output:
