I'm trying to get order details with WP_Query, this must be work with an ajax call for pagination without page reload. The problem is that I get an error when I try to put some variables, such as: $order_id = $order->get_id(); or $items = $order->get_items();.
The error in google console: POST https://mywebsite.com/wp-admin/admin-ajax.php 500
As @Sadoo suggested, if I put $order_id = get_the_ID(); instead of $order_id = $loop->post->ID; the error in google console disappears.
At this point I should be able to see the details of the orders such as the ID for example, but I still don't get any results. I think the problem is the query because in with var_dump($loop); i get null. Why is this happening ?

If instead of using a WP_Query I use a SQL Query everything works fine. However I am trying to use WP_Query as I am more familiar with it. Below is the working query that returns the results correctly.
//--SQL Query--//
// Set the table where we will be querying data
$table_name = $wpdb->prefix . "posts";
// Query the posts
$loop = $wpdb->get_results($wpdb->prepare("
SELECT * FROM " . $table_name . " WHERE post_type = 'shop_order' AND post_status = 'wc-completed' ORDER BY post_date DESC LIMIT %d, %d", $start, $per_page ) );
// At the same time, count the number of queried posts
$count = $wpdb->get_var($wpdb->prepare("
SELECT COUNT(ID) FROM " . $table_name . " WHERE post_type = 'post' AND post_status = 'publish'", array() ) );
// Loop through each order post object
foreach( $loop as $customer_order ){
$order_id = $customer_order->ID; // The Order ID
// Get an instance of the WC_Order Object
$order = wc_get_order( $customer_order->ID );
$orders_id = $order->get_id();
echo '<span>#'. esc_attr($orders_id) .'</span>';
}
the_post() returns True when finished. as a result of calling setup_postdata().
go ahead and try $order_id = get_the_ID(); instead of $order_id = $loop->post->ID; and see if it works.
Update 1: I did some cleaning up on your code. hope this is more understandable:

$per_page = 4;
// Okay, lets make a query including shop orders that are completed.

'post_type' => 'shop_order',
