Can't resolve '@/util' in when compiling external package

• Laravel Version: 9.19.0
• Nova Version: 4.12.2
• PHP Version: 8.0.13
• Operating System and Version: Mac OS 12.4
• Browser type and version: Chrome 103.0.5060.114
• Reproduction Repository: https://github.com/Natterhub-Ltd/nova-fields
• WIP Upgrade Commit: Natterhub-Ltd/nova-fields@2405b8e

Description:

When running the npm run prod command on the package above, I get the below screenshot:

This package was originally a Nova 3 package which I'm upgrading to Nova 4 to suit our business needs so I'm not entirely sure what I've missed as part of the upgrade process. Any ideas?

Detailed steps to reproduce the issue on a fresh Nova installation:

1. clone provided repository
2. run composer install && npm ci && npm run nova:install
3. within vendor/laravel/nova
   1. run mv webpack.mix.js.dist webpack.mix.js
   2. run npm run dev
4. within the root of the cloned repo, run npm run prod

Edit 1: Added link to commit of initial upgrade work for easier viewing

Update: I have narrowed the issue to be whenever you include a mixin from the Nova source that used to be in the laravel-nova npm package (such as InteractsWithDates).

The public API for 3rd party packages are only mixins defined under resources/js/mixins/packages.js. You need to resolve @/utils on your own if you need this.
