Include [meta_data] in an api from Woocommerce order - woocommerce

Question

Hello I have a pluging API that generates a JSON of the seller order list in an object list like. I would like to add the meta data of the order
The code below is the function responsible for the json data :
{
$profile_pic = [];
$api = new WC_REST_Orders_V1_Controller();
$results = [];
if (
is_plugin_active(
"wc-multivendor-marketplace/wc-multivendor-marketplace.php"
)
) {
global $wpdb;
$page = 1;
$per_page = 10;
if (isset($request['page'])) {
$page = sanitize_text_field($request['page']);
if(!is_numeric($page)){
$page = 1;
}
}
if (isset($request['per_page'])) {
$per_page = sanitize_text_field($request['per_page']);
if(!is_numeric($per_page)){
$per_page = 10;
}
}
$page = ($page - 1) * $per_page;
$table_name = $wpdb->prefix . "wcfm_marketplace_orders";
$sql =
"SELECT * FROM " . $table_name . " WHERE vendor_id = $user_id AND is_trashed != 1";
if (isset($request["status"])) {
$status = sanitize_text_field($request["status"]);
$sql .= " AND order_status = '$status'";
}
if (isset($request["search"])) {
$search = sanitize_text_field($request["search"]);
$sql .= " AND order_id LIKE '$search%'";
}
if (isset($request['name'])) {
$results = [];
$table_name2 = $wpdb->prefix . "users";
$name = sanitize_text_field($request['name']);
$sql2 = "SELECT {$table_name2}.ID";
$sql2 .= " FROM {$table_name2}";
$sql2 .= " WHERE {$table_name2}.display_name LIKE '%$name%'";
$sql2 .= " ORDER BY {$table_name2}.display_name";
$users = $wpdb->get_results($sql2);
if (count($users) > 0) {
$user_str = array();
foreach ($users as $user) {
$user_str[] = $user->ID;
}
$user_strr = implode(',', $user_str);
$sql .= " AND `{$table_name}`.customer_id IN ({$user_strr})";
} else {
return new WP_REST_Response(
[
"status" => "success",
"response" => [],
],
200
);
}
}
$sql .= " GROUP BY $table_name.`order_id` ORDER BY $table_name.`order_id` DESC LIMIT $per_page OFFSET $page";
$items = $wpdb->get_results($sql);
foreach ($items as $item) {
$order = wc_get_order($item->order_id);
//$order1 = wc_get_order($item->order_id);
//$order2 = wc_get_order( $order_id );
//$order_id = $order1->get_id($item);
//$order_data = $order1->get_meta('_barcode_text');
//$final_array = array_values($order_data);
if (is_bool($order)) {
continue;
}
$response = $api->prepare_item_for_response($order, $request);
$order = $response->get_data();
// $order2 = WC_REST_Orders_V1_Controller($order1);
$order3=$order2;
//$my_var = get_post_meta( $order_id, '_wcfmd_delvery_times', true );
//$meta_data = $item->get_formatted_meta_data('_', true);
//$order_data = $order1->get_meta('_wcfmd_delvery_times');
$count = count($order["line_items"]);
$order["product_count"] = $count;
$order["Hello"] = 'zf';
$order["meta_data"]=$order_id;
$line_items = array();
for ($i = 0; $i < $count; $i++) {
$product_id = absint(
$order["line_items"][$i]["product_id"]
);
$product = get_post($product_id);
$product_author = $product->post_author;
if (absint($product_author) != absint($user_id)) {
continue;
}
$commission_data = get_post_meta($product_id, '_wcfmmp_commission', true);
if(!empty($commission_data)){
$order["line_items"][$i]['commission'] = $commission_data;
}
$image = wp_get_attachment_image_src(
get_post_thumbnail_id($product_id)
);
if (!is_null($image[0])) {
$order["line_items"][$i]["featured_image"] = $image[0];
}
$order_item = new WC_Order_Item_Product($order["line_items"][$i]["id"]);
$order["line_items"][$i]["meta"] = $order_item->get_meta_data();
if (is_plugin_active('wc-frontend-manager-delivery/wc-frontend-manager-delivery.php')) {
$table_name = $wpdb->prefix . "wcfm_delivery_orders";
$sql = "SELECT delivery_boy FROM `{$table_name}`";
$sql .= " WHERE 1=1";
$sql .= " AND product_id = '{$product_id}'";
$sql .= " AND order_id = '{$item->order_id}'";
$users = $wpdb->get_results($sql);
if (count($users) > 0) {
$user = get_userdata($users[0]->delivery_boy);
$order["line_items"][$i]['delivery_user'] = [
"id" => $user->ID,
"name" => $user->display_name,
"profile_picture" => $profile_pic,
];
}
}
$line_items[] = $order["line_items"][$i];
}
$order["line_items"] = $line_items;
$results[] = $order;
}
}
This is the current Json data
