The magic method Instamojo\Instamojo::__wakeup() must have public visibility

[karthick003]

i am trying to integrate in laravel 9 ,php version 8.1.0.
i have installed the wrapper through composer require instamojo/instamojo-php
then in controller
public function pay(Request $request){

 $api = new \Instamojo\Instamojo(
        config('services.instamojo.api_key'),
        config('services.instamojo.auth_token'),
        config('services.instamojo.url')
    );

try {
    $response = $api->paymentRequestCreate(array(
        "purpose" => "FIFA 16",
        "amount" => $request->amount,
        "buyer_name" => "$request->name",
        "send_email" => true,
        "email" => "$request->email",
        "phone" => "$request->mobile_number",
        "redirect_url" => "http://127.0.0.1:8000/pay-success"
        ));
        
        header('Location: ' . $response['longurl']);
        exit();
}catch (Exception $e) {
    print('Error: ' . $e->getMessage());
}

}

Go to your vendor/instmoja/instmoja-php/src/instamozo.php and make it public from private
as like this public function __wakeup() {}

i am also stuck with the error but it is private for a reason(i don't know why) right, and also, i think manually changing things in vendor folder is bad habit.
