如何退还单个资产OhMyBrew Laravel Shopify

我正在尝试使用ohmybrew / laravel-shopify在以下代码中以Laravel中的单个Shopify资产的形式获取对象：

$asset = $shop->api()->rest('GET', '/admin/api/'.ShopifyApp::api()->getVersion().'/themes/80166092888/assets.json?asset[key]=snippets/collection-grid-item.liquid');

我认为$ asset的结果应该是Shopify资产，但是当我print_r（$ asset）时，我得到了：

我可以使用以下方法正确检索所有资产的列表：

$assets = $shop->api()->rest('GET', '/admin/api/'.ShopifyApp::api()->getVersion().'/themes/80166092888/assets.json');

但是此对象不包含我需要的信息-特别是每项资产的价值。

Shopify文档详细介绍了这是检索单个资产的正确方法：

GET /admin/api/2019-10/themes/#{theme_id}/assets.json?asset[key]=templates/index.liquid&theme_id=828155753

而且我可以成功地从浏览器发出GET请求，以检索所需的信息。

不知道我在PHP / Laravel / OhMyBrew方面做错了什么。
