i am getting the following error . i can not trace why this error is generating. i am using this library for push notification in other project it worked but it shows that error in other. Please help.

public function initializeConfig($service)
{
    if (function_exists('config_path') &&
        file_exists(config_path('pushnotification.php')) &&
        function_exists('app')
    ) {
        $configuration = app('config')->get('pushnotification');
    } else {
        $configuration = include(__DIR__ . '/Config/config.php');
    }

    if (!array_key_exists($service, $configuration)) {
        throw new PushNotificationException("Service '$service' missed in config/pushnotification.php");
    }
    return $configuration[$service];
}

What Laravel version are you using?

Could you confirm the pushnotification.php config file was created?

[MoaizP]

Using laravel version 5.6.39
yes file is created.

Could run the below command and try again?

php artisan config:cache
