Laravel Custom Middleware: ERR_TOO_MANY_REDIRECTS - php

Question

I'm using Laravel Breeze + Inertia (React) and want to implement custom auth.
I'm having infinite redirection (ERR_TOO_MANY_REDIRECTS) when visiting /dashboard on this middleware.
Route::get('register', [RegisteredUserController::class, 'create'])
->name('register');
Route::post('register', [RegisteredUserController::class, 'store']);
Route::get('login', [AuthenticatedSessionController::class, 'create'])
->name('login');
Route::post('login', [AuthenticatedSessionController::class, 'store']);
Route::middleware(['custom_auth'])->group(function () {
Route::get('/dashboard', function () {
return Inertia::render('Dashboard');
})->name('dashboard');
});
class CustomAuthMiddleware
{
public function handle(Request $request, Closure $next)
{
if (session()->has('user_data')) {
return redirect(RouteServiceProvider::HOME);
}
return $next($request);
}
}

This works:
namespace App\Http\Middleware;
class RedirectIfAuthenticated
{
public function handle(Request $request, Closure $next, ...$guards)
{
if (session()->has('user_data')) {
return redirect()->route('users.index');
}
return $next($request);
}
}
namespace App\Http\Middleware;
class CustomAuthMiddleware
{
public function handle(Request $request, Closure $next)
{
if (session()->has('user_data')) {
return $next($request);
}
return redirect('login');
}
}
Route::middleware('guest')->group(function () {
Route::get('register', [AuthController::class, 'register'])
->name('register');
Route::post('register', [AuthController::class, 'registerPost']);
Route::get('login', [AuthController::class, 'login'])
->name('login');
Route::post('login', [AuthController::class, 'loginPost']);
});
Route::middleware('custom_auth')->group(function () {
Route::get('/', function () { return redirect()->route('users.index'); });
Route::resource('users', UserController::class);
});
