Argument 1 passed to CodeIgniter must be an instance of Config\App, null given

Hi guys

I'm cloning a private repository from github, which contains a CodeIgniter App
I've created a virtualhost, pointing to public folder,
Then threw composer update command, and all went fine
Then set 777 to writable/ *

When loading virtualhost's url, I'm getting the following error

Code:

Fatal error: Uncaught TypeError: Argument 1 passed to CodeIgniter\CodeIgniter::__construct() must be an instance of Config\App, null given, called in /media/ci/vendor/codeigniter4/framework/system/Config/Services.php on line 139 and defined in /media/ci/vendor/codeigniter4/framework/system/CodeIgniter.php:147 Stack trace: #0 /media/ci/vendor/codeigniter4/framework/system/Config/Services.php(139): CodeIgniter\CodeIgniter->__construct() #1 /media/ci/vendor/codeigniter4/framework/system/Config/BaseService.php(248): CodeIgniter\Config\Services::codeigniter() #2 /media/ci/vendor/codeigniter4/framework/system/Config/BaseService.php(189): CodeIgniter\Config\BaseService::__callStatic() #3 /media/ci/vendor/codeigniter4/framework/system/Config/Services.php(134): CodeIgniter\Config\BaseService::getSharedInstance() #4 /media/ci/vendor/codeig in /media/ci/vendor/codeigniter4/framework/system/CodeIgniter.php on line 147

I've php 7.4.23 running with Apache on Ubuntu 18.04

Any clues? Thanks a lot in advance
