我已经使用app engine service来将我的React应用程序部署到我曾经使用过create-react-app的地方。我按照以下步骤部署了应用程序
gcloud auth login
gcloud config set project travelappfrontend
gcloud app deploy
在此过程中，它没有显示任何错误，而是显示了成功消息。但是，当我打开它生成的URL时，它会花费很多时间并说502 bad gateway。我还需要考虑其他事项吗？
这是我的app.yaml
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，我只会得到与eslint相关的警告
这是详细的日志。我通过停止以前的版本再次创建了一个新的。我使用gcloud app logs read
