在AWS Lambda（AL2023）运行Headless Playwright WebKit遇断言错误求助

我正在尝试在运行AL2023系统的AWS Lambda函数中使用Headless Playwright WebKit，已知Playwright官方不支持该环境。

操作步骤 #

• 在同版本AL2023的EC2实例上通过npm安装playwright-webkit
• 使用ldd、strace和LD_DEBUG=libs工具分析WebKit二进制文件的系统依赖，将所需依赖库打包为ZIP后上传至Lambda作为层

测试脚本 #

// script.js
const { webkit } = require('playwright');
(async () => {
  const browser = await webkit.launch({
    executablePath: '/home/ec2-user/webkit/bin/MiniBrowser',
    headless: true,
    args: ['--automation']
  });
  const page = await browser.newPage();
  await page.goto('https://www.google.com');
  console.log(await page.title());
  await browser.close();
})();

该脚本在EC2实例上可正常运行，说明依赖库已齐全，但在Lambda中执行时抛出如下错误：

补充信息 #

• 未在网上找到其他用户遇到此Assertion 'isConstructed()' failed错误的案例，仅在WPEBackend-fdo仓库看到一个未回复的帖子
• 根据源码，ws.cpp文件与音视频渲染相关，但我认为无头环境下不应需要该模块
• 已尝试设置以下环境变量来禁用图形渲染，但因缺乏文档不确定是否有效：
  • LD_LIBRARY_PATH = /tmp/browser/webkit/lib:/tmp/browser/webkit/sys/lib:${LD_LIBRARY_PATH}
  • GIO_EXTRA_MODULES = /tmp/browser/webkit/sys/lib/gio
  • WEBKIT_EXEC_PATH = /tmp/browser/webkit/bin
  • WEBKIT_INJECTED_BUNDLE_PATH = /tmp/browser/webkit/lib
  • LIBGL_ALWAYS_SOFTWARE = true
  • WEBKIT_DISABLE_COMPOSITING_MODE = 1
  • WEBKIT_DISABLE_WAYLAND = 1
  • WEBKIT_DISABLE_WEBGL = 1
  • WPE_BACKEND = headless
  • WPE_INIT_VIEW_BACKEND = headless

恳请各位提供解决建议。
