[solved] Agile Web Development with Rails 8: Headless Chrome is already the default for Rails 8 (p 189)

The section that instructs users to change the using: :chrome to using: :headless_chrome at the top of page 189 is no longer needed. rails new generates apps with headless Chrome for Rails 8 (so that the GitHub actions it comes with by default will work).

Good catch! Thanks!
