CodeIgniter 4 redirect function not working

In codeigniter 4 redirect()->to() returns a RedirectResponse object, which you need to return from your controller to do the redirect.

for ex.

class Home extends BaseController {
    public function index() {
        return redirect()->to('');

I use this and it works

return redirect()->to(site_url());

as per CI 4


return redirect()->to('url'); 

if you are using route then use

return redirect()->route('named_route');
