amazon-web-services - 是什么导致 AWS Lambda 上出现此 Runtime.ExitError？

Question

我正在尝试在 Lambda 上测试一个函数，但是当我测试它时，我得到一个 Runtime.ExitError:

会是什么原因？

{"errorType": "Runtime.ExitError", "errorMessage": "RequestId:
 0dfeb7be-012d-43b7-8674-665bfd8b2bc2 Error: Runtime exited with error: exit status 7" }

Answer 1

我在研究中发现了这个页面，并认为我会发布我的问题/解决方案。没有得到确切的退出代码 7，但具体来说:

Error: Runtime exited with error: signal: killed Runtime.ExitError

没有其他错误、日志等。上一行给出了解决方案:

Memory Size: 1024 MB Max Memory Used: 1024 MB

我的 Lambda 函数执行时内存不足。增加最大内存，问题解决。如果看到 Runtime.ExitError，内存是个好东西。
