Integration with Payment Plugin (iPay88)

I made a public function at wt-woocommerce-sequential-order-numbers/includes/class-wt-advanced-order-number.php and entered this code that you provided:

public function find_order_by_order_number( $order_number ) {

		$args    = array(
            'post_type'      => 'shop_order',
            'post_status'    => 'any',
            'meta_query'     => array(
                array(
                    'key'        => '_order_number',
                    'value'      => $order_number,  //here you pass the Order Number
                    'compare'    => '=',
                )
            )
        );
        $query   = new WP_Query( $args );
        if ( !empty( $query->posts ) ) 
        {
            $order_id = $query->posts[ 0 ]->ID;
        }
        else
        {
        	$order_id = $order_number;
        }
		return $order_id;
	}

and then added this code on the payment gateway private function get_order_id [the first code snippet I provided on this thread]

elseif ( class_exists( 'Wt_Advanced_Order_Number' ) ) {
			global $wt_advanced_order_number;

			$order_id = $wt_advanced_order_number->find_order_by_order_number( $order_number );

			if ( 0 === $order_id ) {
				$order_id = $order_number;
			}

		}

`

Everything is fine except for the part where payment is completed and will redirect already to the Thank You page. This is the error that I am getting:
