Thank you any good news?

I’m creating a woocommerce plugin for an e-payment option specifically for a Lebanese bank based on sark migs, I reached a point where I am redirected to the bank portal, and once the test card number is used it gets me back to my website with ” thank you your order has been received” (which is not my success message) woocommerce keeps the payment as pending and the bank portal doesn’t update the transaction. the returned URL in woocomerce shows this error

Warning: call_user_func_array() expects parameter 1 to be a valid callback, array must have exactly two members in C:\wamp\www\wordpress3\wp-includes\plugin.php on line 525

Is my problem related to this error ( I only modified in sark plugin and not in the functions) or is it related to the idea of authenticating the callback URL in my bank’s portal ( I have read this part somewhere abt paypal)

Below is my code, any help is appreciated!

if ( ! defined( 'ABSPATH' ) ) { exit; }

add_action('plugins_loaded', 'sark_migs_init', 0);
