Joomla 4 WebAssetManager error

Question

I'm a little confused on the documentation for adding assets to my component, and getting an error message:

There is no "com_supersite.supersite" asset of a "script" type in the registry.

I have a media reference in my manifest file:

<media destination="com_supersite" folder="media">
    <file>joomla.assets.json</file>
    <folder>css</folder>
    <folder>js</folder>
</media>

My joomla.assets.json file, which I think should register my assets:

{
  "$schema": "https://developer.joomla.org/schemas/json-schema/web_assets.json",
  "name": "com_supersite",
  "version": "4.0.0",
  "description": "Joomla CMS",
  "license": "GPL-3.0-or-later",
  "assets": [
    {
      "name": "com_supersite.supersite",
      "type": "script",
      "uri": "com_supersite/supersite.js",
      "dependencies": [
        "core"
      ],
      "attributes": {
        "defer": true
      }
    },
    {
      "name": "com_supersite.supersite",
      "type": "style",
      "uri": "com_supersite/supersite.css"
    }
  ]
}

And then trying to use the script asset in my component view:

<?php

use Joomla\CMS\Factory;

\defined('_JEXEC') or die('Restricted access');


/** @var \Joomla\CMS\WebAsset\WebAssetManager $wa */
$wa = Factory::getApplication()->getDocument()->getWebAssetManager();

$wa->useScript('com_supersite.supersite');

Answer 1

Per documentation, the web asset registry file must be named joomla.asset.json, not joomla.assets.json to be loaded automatically.

Answer 2

@Sharky, you were right to call my original answer incorrect. I wasn't paying enough attention to the names in the asset file compared to the error message received.
I updated the joomla.asset.xml file, and now I don't need to register the scripts.

{
  "$schema": "https://developer.joomla.org/schemas/json-schema/web_assets.json",
  "name": "com_supersite",
  "version": "4.0.0",
  "description": "Joomla CMS",
  "license": "GPL-3.0-or-later",
  "assets": [
    {
      "name": "supersite",
      "type": "script",
      "uri": "com_supersite/supersite.js",
      "dependencies": [
        "core",
        "jquery"
      ],
      "attributes": {
        "defer": true
      }
    },
    {
      "name": "supersite",
      "type": "style",
      "uri": "com_supersite/supersite.css"
    }
  ]
}

Component View:

<?php

use Joomla\CMS\Factory;
use Joomla\CMS\HTML\HTMLHelper;

\defined('_JEXEC') or die('Restricted access');


/** @var CMSApplication $app */
$app = Factory::getApplication();

$wa = $app->getDocument()->getWebAssetManager();

$wa->useStyle('supersite')
    ->useScript('supersite');
