Error NaN: undefined Reason: undefined: Getting error after 1 minute

问题

我已经开发了一个Spring Boot应用程序，使用React作为前端。我正在将一个PDF文件流返回到浏览器。然而，当请求发送到控制器时，如果处理时间超过1分钟，屏幕上会显示错误 Error NaN: undefined Reason: undefined

我已经尝试在前端和后端增加了超时时间，但没有成功。我不确定这是否与超时有关。有人可以帮忙吗？以下是堆栈跟踪。

I have developed a Spring boot application, with React as Frontend. I'm Steaming a PDF back to the browser. However, when a Request goes to the Controller, and when the processing takes longer than 1 minute, I get an error on the Screen Error NaN: undefined Reason: undefined

I have tried increasing the timeout in both front as well as backend, but no luck. I'm not sure if this is related to timeout or not. Can someone please help. Below is the stack trace.

SOLVED : 问题出在负载均衡器的超时值上。它被设置为1分钟。一旦增加了这个值，超时问题得以解决。

英文:

SOLVED : The problem was with the Load Balancer's time out value. It was set to 1 minute. Once this value was increased, the timeout problem got solved.
