CRITICAL Uncaught Error: Call to a member function get_meta() on null

Question

I have CRITICAL Uncaught Error: Call to a member function get_meta() on null here

$Sperson = $item_val->get_meta( 'Sales Person', true );

This is preventing payments going through on the checkout page. An empty notification error is shown on the checkout page when a user clicks pay and complete order. When the below code is removed, payments go through.

The code prints the sales person to the order email

add_action('woocommerce_checkout_create_order_line_item','rw4y_add_custom_order_line_item_meta',10,4);
function rw4y_add_custom_order_line_item_meta($item, $cart_item_key, $values, $order){
    if (array_key_exists('shop_manager_id', $values)) {
        $custom_details = $values['shop_manager_id'];
        $shop_obj = get_user_by('id', $values['shop_manager_id']);  
        $item->add_meta_data('SID',$values['shop_manager_id'] );
        $item->add_meta_data('Sales Person',"[".$values['shop_manager_id']."] - ".$shop_obj->display_name );
        $SIID = $values['shop_manager_id'];
        if($SIID!='' &&  (get_post_meta( $order->id, 'SID', true ))=='')
        {                        
            update_post_meta( $order->id,'SID', $SIID );    
            $Sperson = $item_val->get_meta( 'Sales Person', true );
            update_post_meta($order->id, 'Sales Person', $Sperson );
        }   
    }
}

`$item_val` is not defined anywhere. Did you mean to use `$item`? — aynber, Aug 19 '22 at 13:32
