我有一个包含 puppeteer 网络爬虫的 docker 图像。当我构建和运行它时，它在我的本地机器上运行良好。它还在云构建中构建良好，部署到云运行并启动 http 服务器。但是，当我运行处理 puppeteer 实例的 cron 作业之一时，它超时并显示以下错误消息：

(node:13) UnhandledPromiseRejectionWarning: TimeoutError: Timed out after 30000 ms while trying to connect to Chrome! The only Chrome revision guaranteed to work is r706915
