What is this about?
@feathersjs/vuex is incorrectly packaged. Please contact the package author to fix.

The package in question is @feathersjs/vuex
https://unpkg.com/browse/@feathersjs/vuex@4.0.1-pre.16/

{
	  name: "@feathersjs/vuex",
	  description: "FeathersJS, Vue 3, and Nuxt for the artisan developer",
	  version: "4.0.1-pre.16",
	  homepage: "https:vuex.feathersjs.com",
	  main: "dist/",
	  module: "dist/",
	  types: "dist/"

I can't see anything wrong with it. The message pops up every time you reload vite. https://stackblitz.com/edit/feathersjs-wy4w68?file=vuex.json That sandbox has a custom vuex.json that gets copied to @feathersjs/vuex/package.json for debugging. So far I can't get the message to go away.

I've never seen a package list a directory rather than file as the entry point. I have no idea whether that's valid. But assuming it is, there appears to be another issue here. Both main and module list the same ESM entry point, but the package.json neither specifies "type": "module" nor uses an .mjs extension, so I don't think Node.js would load this package (though it would work with many bundlers and Vite is able to convert the code to work while letting you know about the issue)

Good call... the error message could be a little more useful. The following package.json header fixed it

{
  "name": "@feathersjs/vuex",
  "description": "FeathersJS, Vue 3, and Nuxt for the artisan developer",
  "version": "4.0.1-pre.16",
  "homepage": "https:vuex.feathersjs.com",
  "main": "dist/index.js",
  "types": "dist/",
  "exports": {
    "import": "dist/index.js"
  },
