Javascript 502使用应用程序引擎服务部署时网关损坏

我已使用

应用程序引擎服务

将我的react应用程序部署到使用

创建react应用程序

的位置。我部署了我的应用程序如下

gcloud身份验证登录

gcloud配置集项目travelappfrontend

gcloud应用程序部署

在这个过程中，它没有向我显示任何错误，而是得到了成功的消息。但是，当我打开它生成的url时，它会消耗很多时间，并显示

502坏网关

。我需要考虑其他的事情吗？

这是我的应用程序

service: frontend-app
runtime: nodejs
env: flex
handlers:
  - url: /
    static_files: build/index.html
    upload: build/index.html
  - url: /
    static_dir: build

当我看到日志时，只会收到与eslint相关的警告

下面是详细的日志。我通过停止以前的版本再次创建了一个新版本。我使用

gcloud应用程序日志生成的日志已读取

添加更多的console.log（）并提供精确的日志<代码>502错误网关

可能由于多种原因引发错误。应用程序引擎日志中有日志吗？最好从appengine提供一些控制台日志。还可以在详细模式下尝试

gcloud components update1和
gcloud app deploy`。如何从app engine执行控制台日志？您的意思是说，
gcloud应用程序日志已读
？最简单的选择--进入云控制台>应用程序引擎>服务>右侧的表视图，诊断列>下拉列表>日志。。。。您可能需要单击“加载更新的日志”。[链接]我在日志中只看到与eslint相关的问题，这也是eslint警告。Localhost可能会连接您的Prod环境。如果您的系统具有Internet连接，您的本地环境也可能连接Google API。但是这并不意味着你的应用引擎可以连接你的PROD服务器。您是否尝试从App Engine PING生产服务器主机名？如果没有，请尝试一下。您可以在这里查看-[链接]
