Question: Below as an array instead of object?

I am also having troubles with this object which is not showing several objects. It is showing only the first one.

That's a good question. I will take a look at this soon.

Hi guys, it's cause in getMenuItems() method src/Plugin/rest/resource/RestMenuItemsResource.php line 240 the array key is a string instead integer, when the serializer convert it in JSON the array is converted to object.

If you change :

      $items[$item_name] = [
        'key'      => $item_name,
        'title'    => $org_link->getTitle(),
        'uri'      => $uri,
        'alias'    => ltrim($alias, '/'),
        'external' => $external,
        'absolute' => $absolute,
        'weight'   => $org_link->getWeight(),
        'expanded' => $org_link->isExpanded(),
        'enabled'  => $org_link->isEnabled(),
        'uuid'     => $uuid,
        'options'     => $options,
      ];

to :

      $items[] = [
        'key'      => $item_name,
        'title'    => $org_link->getTitle(),
        'uri'      => $uri,
        'alias'    => ltrim($alias, '/'),
        'external' => $external,
        'absolute' => $absolute,
        'weight'   => $org_link->getWeight(),
        'expanded' => $org_link->isExpanded(),
        'enabled'  => $org_link->isEnabled(),
        'uuid'     => $uuid,
        'options'     => $options,
      ];

After the serialization, it's a array instead object.

I've applied the patch. @mattferderer and @tpzurdo could you check if the dev version fixes the problem?

I've patch too quickly, i've miss to change 'below' implementation.

+      end($items);
+      $item_key = key($items);
+
       if (!empty($item_value['below'])) {
-        $items[$item_name]['below'] = [];
-        $this->getMenuItems($item_value['below'], $items[$item_name]['below']);
+        $items[$item_key]['below'] = [];
+        $this->getMenuItems($item_value['below'], $items[$item_key]['below']);
       }

I've just pushed the last addition.

This is fixed in the upcoming 8.x-1.5 release.
