Your configuration files are not serializable.

[leonardyrj]

Quando coloco no arquivo de configuração config/laravelpagseguro.php essa configuração

'notification' => [ 'callback' => function ($information) { // Callable //\Log::debug(print_r($information, 1)); }, 'credential' => 'default', // Callable 'route-name' => 'pagseguro.notification', // Criar uma rota com este nome ],

Quando dou o comando no terminal config:cache ocorre esse problema:

` LogicException : Your configuration files are not serializable.

71| throw new LogicException('Your configuration files are not serializable.', 0, $e);
