CI 4.18 -> 4.20 causes RouterException

Hi all,
I am upgrading from 4.18 to 4.20.
But now I receieve numerous RouterExceptions.
For example: Controller or its method is not found: \App\Controllers\Login::index
This is de routes.php rule:

PHP Code:

$routes->get('/beheer', 'Login::index'); 


And I do have a app/Controllers/Login.php file with an index() method in it.
I can't seem to find anything in the changelog what will cause this behaviour.

Check your routes:

Code:

$ php spark routes
$ php spark routes | grep beheer

ci-phpunit-test | CodeIgniter Testing Guide | CodeIgniter 3 to 4 Upgrade Helper

| GET | beheer | \App\Controllers\Login::index | | toolbar |

It's present....
Only difference.... App is uppercase, and my folder name is app (lowecase).
Can that be the problem?

No.

Code:

Controller or its method is not found: \App\Controllers\Login::index

This error occurs when the controller class can't be autoloaded.

Did you customize something in autoload configuration?

Yes, unless there is a bug we don't know, there is no change in that area.

I think I've found the problem...
It's an url_to() issue.
I have this line to redirect to the dashboard when a user is already logged in:

PHP Code:

return redirect()->to(url_to('\App\Controllers\backend\Dashboard::index')); 


This line throws the error.
But when I change it to:

PHP Code:

return redirect()->to(url_to('backend\Dashboard::index')); 


It works, but I have many uses of url_to(), it would be quite some work to modify all these occurences, and with a risk of forgetting one.

Does anyone know, why this is a problem all of a sudden?
And is there a way of making it work like it used to work?

Sorry, it seems a bug.
'\App\Controllers\backend\Dashboard::index' should work.

Can you try this patch?

Yep, that seems to work!
Thanks.

Is this fix going to be in next versions of CI?

I sent a PR to fix this: https://github.com/codeigniter4/CodeIgniter4/pull/6104
