Answer 1

I think when you called Middleware you used a square bracket, you have used an array for submitting the parameter to the middleware, use the below code
Route::middleware([Permission::class])->group(function($id){
});
For submitting multiple parameters through middleware use this code:
Route::get('/', function () {
//
})->middleware(['first', 'second']);
For passing single middleware use this:
Route::get('/profile', function () {
//
})->middleware('auth');

The issue is that the middleware is expecting a parameter and you aren't supplying it.
If you want your middleware to have an additional parameter $id, then route should be like this:
Route::middleware([Permission::class.':id_value_goes_here'])->group(function () {
});
If you need the ID to be a dynamic parameter based on a route parameter (e.g. Route::get('/posts/$id', ...)) or something passed to the request, then you should omit the extra parameter from the middleware handle()'s method signature:
public function handle(Request $request, Closure $next)
{
$id = $request->id; // $id will now get correctly set
}
