Description

In Laravel 12.0.10, the closure passed to the withMiddleware() call now has a void return type (laravel/laravel#6628). Because of that, while installing Jetstream, the installMiddleware() method cannot find ->withMiddleware(function (Middleware $middleware) { (it's ->withMiddleware(function (Middleware $middleware): void { now) and add middleware to the web group.

Steps To Reproduce

laravel new jetstream-inertia-test --no-interaction
cd jetstream-inertia-test
composer require laravel/jetstream
php artisan jetstream:install inertia

See that in bootstrap/app.php, there's nothing added to the web middleware group. There should be

$middleware->web(append: [
    \App\Http\Middleware\HandleInertiaRequests::class,
    \Illuminate\Http\Middleware\AddLinkHeadersForPreloadedAssets::class,
]);
