assets 404 after following install guide for importmaps

[itsyoshio]

After following the Installation Guide for the Importmaps variant, any page load results in loads of index.js and other 404 errors, all of various *.js files.

These seemingly start with Calendar Components but we're talking about various components (~300 of them).

@itsyoshio, I recommend getting the stimulus controllers from https://github.com/PhlexUI/phlex_ui_stimulus/tree/main/controllers and copying them to your project. That's how I'm using them.
