seems like proper error page is missing :D
It's a limitation of Laravel Cloud apparently?
I run into this several times in my apps, solved it by using this:
https://inertiajs.com/docs/v3/advanced/error-handling
It's like inertia needs to be tweak before going to prod, cause errors are still rendered in modals which is not the best UI/UX.
