CI4 Beta 1: function _remap not works properly

I'm having the same issue.

My approach is to "fool" it by placing a dummy function if I'm not messing with Route

Code:

public function parameter1()
{
    // placeholder
}

Anyone has a better idea?

my english is not the best.

in Codeigniter 3 I do:

URL:
/test/parameter1/parameter2/<parameterN>

CI3
called class: Test 
called method:  _remap (I have it function declared).

in Codeigniter 3 all works ok.

but in Codeigniter 4,

with URL:
/test
CI4 call method _remap, woks ok.

but with URL:
/test/parameter1
or URL 
/test/parameter1/parameter2/<parameterN>

show error: ReflectionException "Method App\Controllers\Test::parameter1() does not exist"

-----

Details:
- No setting route additional.
- I try wihtout function index, but it does not affect.

PHP Code:

<?php namespace App\Controllers;

use CodeIgniter\Controller;

class Test extends Controller
{
    public function index()
    {
        echo "Test/index";
    }
    //--------------------------------------------------------------------
    public function _remap($method)
    {
        echo "Test/remap - {$method}";
    }
    //--------------------------------------------------------------------
} 


excuse my english, I appreciate the help. thanks!!
