Can't cache configuration when using logObject

[apokryfos]

I am trying to cache my configuration while also using the default laravel logger in Laravel 8

• steps taken to reproduce the issue
  1. created new laravel project using laravel new estest
  2. Tried setting the logObject configuration setting to the documented \Log::getMonolog() but that does not work (I think that's outdated). I have also tried using 'logObject' => (new \Illuminate\Log\LogManager(app()))->driver()->getLogger(). however when running php artisan config:cache I get an error Your configuration files are not serializable.
• your configuration file(s), where relevant

  'logging' => true,
  'logObject' => (new \Illuminate\Log\LogManager(app()))->driver()->getLogger(),

I would like to just use the same logger I use normally and also cache my configuration.

Not sure I'm missing something here. Is it meant to be possible to cache the configuration when doing this? Is there an alternative?

You can't serialize that value. I believe you would need to make a class with a method that returns that value ... something like:

class Foo
    function getLogObject() {
        return (new \Illuminate\Log\LogManager(app()))->driver()->getLogger();
    }
}

and then pass that in your config as a callable:

'logObject' => [Foo:class, 'getLogObject'],
