Uncaught Error: If you load both jquery_ujs and rails-ujs, use rails-ujs only.

I have a rails 6.1 application that uses jquery. Here is how I'm importing it in my config/webpack/environments.js file:

$: 'jquery/src/jquery',
jQuery: 'jquery/src/jquery',
jquery: 'jquery',
'window.jQuery': 'jquery'

I am trying to use this the stimulus-sortable component from here:
https://stimulus-components.netlify.app/docs/stimulus-sortable/

Which causes this error: Uncaught Error: If you load both jquery_ujs and rails-ujs, use rails-ujs only.

I can resolve the error by either removing jquery entirely, or removing rails ujs from my application.js file.

It appears to be specific to the stimulus-sortable component, although I'm not sure what is causing that to throw this error, as I am not importing jquery-ujs.

Any help or advice would be greatly appreciated. At this point, I'm probably just going to write my own stimulus controller.
