WooCommerce Shortcode For "Order Again" Customer's Last Order - woocommerce

Question

I'm fairly new with this, but I am learning. I am trying to create a shortcode which can be inserted anywhere on the site, allowing the customer to order their previous order again.
In other words, I need to enable the customer to "order again" their last order. Main problem is, when I try this, the site goes blank (white screen).
Any ideas what's wrong here?
add_shortcode( 'order_again', 'matt_order_again' );
function matt_order_again( $order ) {
if ( is_user_logged_in() ) {
$user_id = get_current_user_id();
$customer = new WC_Customer( $user_id );
$last_order = $customer->get_last_order();
if ( $last_order->has_status( 'completed' ) ) {
$actions['order-again'] = array(
'url' => wp_nonce_url( add_query_arg( 'order_again', $order->get_id(), wc_get_cart_url() ), 'woocommerce-order_again' ),
'name' => __( 'Order again', 'woocommerce' ),
);
}
return $actions;
}
}
I have tried adding the global variable for WC.

try this :
add_shortcode( 'order_again', 'matt_order_again' );
function matt_order_again( $order ) {
if ( is_user_logged_in() ) {
$user_id = get_current_user_id();
$customer = new WC_Customer( $user_id );
$last_order = $customer->get_last_order();
if ( $last_order->has_status( 'completed' ) ) {
$actions['order-again'] = array(
'url' => wp_nonce_url( add_query_arg( 'order_again', $last_order->get_id(), wc_get_cart_url() ), 'woocommerce-order_again' ),
'name' => __( 'Order again', 'woocommerce' ),
);
}
return $actions;
}
}
Or if you want to return a button with url for order again using shorcode use this code (edited).
add_shortcode('order_again', 'matt_order_again');
function matt_order_again($order)
{
if (is_user_logged_in()) {
global $woocommerce;
ob_start();
$user_id = get_current_user_id();
$customer = new WC_Customer($user_id);
$last_order = $customer->get_last_order();
if(!$last_order){
return;
}
if ($last_order->has_status('completed')) {
$url = wp_nonce_url(add_query_arg('order_again', $last_order->get_id(), wc_get_cart_url()), 'woocommerce-order_again');
echo '' . __('Order Again', 'woocomerce') . '';
}
$contents = ob_get_contents();
ob_end_clean();
return $contents;
}
}
