David Kimura PRO said over 1 year ago on Record Audio to Active Storage :
  Jeremy Bray I just set this up again and it seemed to work in a Rails 7 application. The only changes that I had to make from the show notes was

# Terminal
yarn add @rails/activestorage

# application.js
import * as ActiveStorage from "@rails/activestorage"
ActiveStorage.start()

Is there something that you're experiencing different?
