自定义管理网格在我的Magento 2应用中未显示任何数据

Question

当前，我正在创建一个新的自定义网格，以在管理面板中显示“客户”的特定属性（类似于“管理面板->客户->所有客户”中的网格，但仅显示客户ID，客户名称，电话，验证状态和许可证号）。

当我完成代码并重新加载页面后，网格不显示任何数据，而只显示了旋转的轮子。

verification status和license number是我通过UpgradeData.php添加到客户的自定义属性

我正在通过uicomponent创建自定义网格。我通读了本教程https://www.mageplaza.com/magento-2-module-development/create-admin-grid-magento-2.html，并利用Alan Storm Pestle.phar代码生成器生成了相关代码。

我的自定义管理网格设置为管理面板->客户->验证

以下文件是我的代码。我不知道哪一部分是错误的，并且会出错。

Pestle.phar也会自动为我创建两个php文件，但是我不确定这是否会导致问题。

happyhackers / customer / Ui / Component / Listing / Column / Happyhackerscustomerverification / PageAction.php

<?php
namespace Happyhackers\Customer\Ui\Component\Listing\Column\Happyhackerscustomerverification;

class PageActions extends \Magento\Ui\Component\Listing\Columns\Column
{
    public function prepareDataSource(array $dataSource)
    {
        if (isset($dataSource["data"]["items"])) {
            foreach ($dataSource["data"]["items"] as & $item) {
                $name = $this->getData("name");
                $id = "X";
                if(isset($item["entity_id"]))
                {
                    $id = $item["entity_id"];
                }
                $item[$name]["view"] = [
                    "href"=>$this->getContext()->getUrl(
                        "happyhackers_customer_verification/grid/edit",["entity_id"=>$id]),
                    "label"=>__("Edit")
                ];
            }
        }

        return $dataSource;
    }    

}

Happyhackers /客户/ Ui /组件/列表/数据提供者/Happyhackers/Customer/Verification.php

<?php
namespace Happyhackers\Customer\Ui\Component\Listing\DataProviders\Happyhackers\Customer;

class Verification extends \Magento\Ui\DataProvider\AbstractDataProvider
{    
    public function __construct(
        $name,
        $primaryFieldName,
        $requestFieldName,
        \Magento\Customer\Model\ResourceModel\Grid\CollectionFactory $collectionFactory,
        array $meta = [],
        array $data = []
    ) {
        parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
        $this->collection = $collectionFactory->create();
    }
}

我希望在管理面板->客户->验证页面中，自定义网格会显示客户ID，客户名称，许可证编号，电话和验证状态。但实际上，它使我返回到内部服务器错误页面。

如果我注释掉di.xml中的内容，至少它将向我显示网格结构，但是在网格单元内什么也没有。
