JavaScript errors with modal code

I’m noticing issues with JavaScript on various pages using the modal code that Caldera actually provides in its own documentation: https://calderaforms.com/doc/opening-caldera-forms-modals-using-javascript/

With WP-Rocket on, I see errors either such as “Uncaught TypeError: Cannot read property ‘open’ of undefined” or “46b248c0afd82b2f7dcb83347d3295b0.js:1529 Uncaught TypeError: jQuery(…).remodal is not a function”. In either case. it’s this code exposing the errors:

<script>
	var inst = jQuery('[data-remodal-id=modal-CF5123456789012]').remodal();
	inst.open();
</script>

For obvious reasons, I changed the modal ID. But you get the idea.

Why is this code throwing errors? Is it due to the minification WP-Rocket produces?
