Redirect issue

Hello,

I am working on a new project with Codeigniter 4.0 beta 4. I set the URL in the configuration file:

PHP Code:

public $baseURL = 'http://localhost/mysite/'; 


If I now use a redirect, the URL will be redirected to an incorrect URL.

PHP Code:

return redirect()->to('/admin'); 


This call redirects to the following URL:

http://localhost/admin

I'd like someone to help me with this problem.

Thanks
Tom
