Vendor:publish --tag=config in Lumen ^8.0 fails with `Unable to locate publishable resources.`

[commadelimited]

I'd like to use this package in a Lumen 8.0 project.

The initial installation appears to work just fine, but when I move to the next stop, vendor:publish, I'm shown an error. I'm working in a clean branch off master:

$ composer require ylsideas/feature-flags

$ php artisan vendor:publish --provider="YlsIdeas\FeatureFlags\FeatureFlagsServiceProvider" --tag=config

I'm comfortable working in Laravel but most of my time has been spent with an existing codebase, rather than being the one installing and configuring new packages. Is there something I'm doing wrong?

Did you get this working? I'm having the same issue.
