Laravel + Vue + Inertia shadcn-vue initialization fails - Erorr validating Tailwind CSS

[booprodusan]

My app is running on 2 subdomains, thus having 2 entry points, both js and css.
I'm using Laravel 12, tailwind 4.

This is how the project files are structured:

However, when running npx shadcn-vue@latest init I get this error:

Keep in mind that my tailwind is working properly, it's just that I get the error when initializing shadcn-vue.

Do you guys know what the solution might be?
I'll post more images of my project configuration if needed.

Hi, make sure you have app.css in this route

resources/css/app.css

Unfortunately doesn't solve it.

Shadcn-vue is currently not compatible with Tailwindcss 4. If you install Tailwind 3, it will work. You can try installing Laravel 12 with the vue starter kit - that will give you a working example, although that still uses the Radix version of Shadcn.
