初始化Google RecaptchaEnterpriseServiceClient时出现HTTP 500错误

我正在网站中集成reCAPCHA，按照对应仓库的README指引，用Composer在服务器上安装了google/cloud-recaptcha-enterprise。

安装步骤 #

cd includes
composer require google/cloud-recaptcha-enterprise
cd ..

测试代码（test.php） #

<?php

error_reporting(E_ALL);

require 'includes/vendor/autoload.php';

use Google\Cloud\RecaptchaEnterprise\V1\Key;
use Google\Cloud\RecaptchaEnterprise\V1\RecaptchaEnterpriseServiceClient;
use Google\Cloud\RecaptchaEnterprise\V1\WebKeySettings;
use Google\Cloud\RecaptchaEnterprise\V1\WebKeySettings\IntegrationType;


$client = new RecaptchaEnterpriseServiceClient();

echo "DONE";
?>

问题现象 #

页面返回HTTP ERROR 500，无任何警告或错误提示。已确认autoloader.php路径正确，且该自动加载器在includes目录下的其他包中运行正常。

我尝试过以下组合，问题依旧：

• Composer2 + PHP8.2
• Composer1 + PHP7.4
  也尝试过不在includes文件夹中安装。

调试操作与结果 #

为排查自动加载问题，修改了test.php：

<?php

error_reporting(E_ALL);

$autoloader = require 'includes/vendor/autoload.php';
print_r($autoloader);
echo "</br></br>";
$results = $autoloader->findFile("Google\\Cloud\\RecaptchaEnterprise\\V1\\RecaptchaEnterpriseServiceClient");
print "Found file for class at: $results</br></br>";

echo $autoloader->loadClass("Google\\Cloud\\RecaptchaEnterprise\\V1\\RecaptchaEnterpriseServiceClient");

use Google\Cloud\RecaptchaEnterprise\V1\Key;
use Google\Cloud\RecaptchaEnterprise\V1\RecaptchaEnterpriseServiceClient;
use Google\Cloud\RecaptchaEnterprise\V1\WebKeySettings;
use Google\Cloud\RecaptchaEnterprise\V1\WebKeySettings\IntegrationType;


$client =  new RecaptchaEnterpriseServiceClient();

echo "DONE";
?>

得到输出如下：

可见自动加载器能找到类文件，但脚本仍无法完成执行，无法创建RecaptchaEnterpriseServiceClient类实例，请求技术帮助。
