我正在尝试使用 Cloud 集成 Whatsapp 聊天机器人，但在尝试部署时出现此错误。我是这部分编码的新手，因此将不胜感激。

您遇到的错误可能是由于您没有侦听传入的 HTTP 请求，或者您正在侦听错误端口上的传入请求。

您可以在Cloud Run 官方文档中看到，您的容器必须在 Cloud Run 定义并在$PORT环境变量中提供的端口上侦听传入的 HTTP 请求。

如果您的容器未能在预期端口上侦听，则修订健康检查将失败，并且修订将处于错误状态，阻塞路由到它的流量。

在 Node.js 中，您可以使用以下代码：

const port = process.env.PORT || 8080;
app.listen(port, () => {
  console.log('Hello world listening on port', port);
});

请让我知道它是否解决了您的问题。
