Cache doesn't work, InfoCache.php throws errors

I'm trying to figure out why my caching isn't working. It's set to filesystem

Code:

public string $handler = 'file';)

I haven't changed anything in the initial app/Config/Cache.php. .env is set to: CI_ENVIRONMENT = development . I haven't found any indication in the help at https://www.codeigniter.com/user_guide/l...ching.html or https://www.codeigniter.com/user_guide/g...ching.html that there are automatic differences depending on the ENV.

In the controller method I use:

Code:

$this->cachePage($this->cacheTTL);

The controller property is defined as:

Code:

protected $cacheTTL = 604800;

Nothing is created under writeable/cache.

In the console,

Code:

php spark cache:info

results in:

CodeIgniter v4.5.2 Command Line Tool - Server Time: 2024-06-16 16:02:35 UTC+02:00

[Error]
Object of class CodeIgniter\Cache\Handlers\DummyHandler could not be converted to string
at SYSTEMPATH\Commands\Cache\InfoCache.php:70

Backtrace:
  1    SYSTEMPATH\CLI\Commands.php:70
      CodeIgniter\Commands\Cache\InfoCache()->run([])

  2    SYSTEMPATH\CLI\Console.php:48
      CodeIgniter\CLI\Commands()->run('cache:info', [])

      CodeIgniter\Boot::runCommand(Object(CodeIgniter\CLI\Console))

  5    ROOTPATH\spark:84
      CodeIgniter\Boot::bootSpark(Object(Config\Paths))

This error should not actually occur because there is a check:

Code:

if ($config->handler !== 'file') {
    CLI::error('This command only supports the file cache handler.');

    return;
}

Does anyone know what's going wrong here? I'm using Windows 11 Pro with a Wamp Server.

Edit:

Code:

var_dump(cache()->isSupported('file'));

=> bool(true)

I do not get it

Solution:

Through further debugging, I discovered that the write protection is always set by Windows Explorer. I was able to solve it using cmd and then

Code:

attrib -r "C:\path\ci4directory\writable" /S /D
