The ALB has been created and a record set has been registered in Route53.已创建 ALB,并已在 Route53 中注册记录集。 I don't know what the cause is because the log doesn't flow on the Cloud Watch.
我不知道是什么原因,因为日志没有在 Cloud Watch 上流动。
If necessary, I will show the application code.如有必要,我将显示应用程序代码。
I have no idea where this error is occurring.我不知道这个错误发生在哪里。
Can anyone tell me?谁能告诉我?
Thank you.谢谢你。

I think that the reason is that the label of deployment did not match我认为原因是部署的label不匹配
