Empty post on basic tutorial, phalcon v4.0.2

In phalcon basic tutorial signup form example, i can fetch data from db so "List the Registered Users" worked, but i cant save any data in non-blank register form .when i disable "notNullValidation" and fields nullable in db table, result is empty rows in database.These empty rows can be listed.

Values cant pass controller to model.It's not a custom code, generated by phalcon devtools or project folder created manually.Every time i get same error below.

Undefined index: REQUEST_URI implies that the $_SERVER superglobal is not filled in properly by your web-server.

Please check the docs on how to configure apache with phalcon: https://docs.phalcon.io/latest/en/webserver-setup#apache

i checked phpinfo() and phalcon apache setup docs , when i'm trying to debug with phpstorm, i can trace $_SERVER variables and values, maybe it's a cli error due no argument,Page is rendered correctly in browser but i got same error in terminal even index page. i have a virtual host directory and dns record in like "bas.ic" in my development machine, and project folder is localhost/basic..htaccess files in project folder not apache main config file. i can call bas.ic bas.ic/signup etc.
but if i try "localhost/basic" or "localhost/basic/signup" gave me below error "BasicController handler class cannot be loaded

0 [internal function]: Phalcon\Mvc\Dispatcher->throwDispatchException('BasicController...', 2)

1 [internal function]: Phalcon\Dispatcher\AbstractDispatcher->dispatch()

2 E:\xampp\htdocs\basic\public\index.php(48): Phalcon\Mvc\Application->handle('/basic/')

3 {main}"

Must we need a default controller which is same name project folder, if i use virtual host, IndexController or any working without any error. Urls in browser developer tool ok, controller and routing seems to be working but posting data not working.
