Angular 7 应用程序在 GAE Flex 环境中工作，但在标准环境中不起作用

Question

在我部署了我的 angular 7 应用程序并尝试在浏览器上打开它后，我收到错误 500。检查日志我发现这个：

A  FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory 
A   1: node::Abort() [node]

问题是，如果您谷歌FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory修复应该将package.json起始行更改为此"start": "node --max_old_space_size=4096 dist/server",。这样，日志中的错误消失了，但页面仍然给出错误 500，现在日志仅显示以下内容：

F  GET 500 0 B 3.3 s Chrome 70 / GET 500 0 B 3.3 s Chrome 70 5cb9a64b00ff0dd3429e5e7b0e0001657e6e6f6c696665000166726f6e74656e643a323031393034313974313333353337000100
A  Node Express server listening on http://localhost:8080 

也许我需要在app.yaml文件中写入更多内容或对其进行更改，现在它看起来像这样：

runtime: nodejs8
env: standard
service: frontend

我的角度应用也是服务器端渲染的，不使用Firebase。

我让它工作了。问题似乎出在 app.yaml 文件中。我不得不将instance_class设置为 F2。如果未设置，则为默认 F1，并且该类中的内存太低。现在我的app.yaml文件看起来像这样：

runtime: nodejs8
env: standard
service: frontend
instance_class: F2
