Describe the bug
The config file will get an issue when running php artisan config:cache

Error:

In ConfigCacheCommand.php line 73:

  Your configuration files are not serializable.


In config.php line 14030:

  Call to undefined method Closure::__set_state()

You may need to update the config file at this line:

'request_salt' => function () {
        return 1234;
    },
