Python Lambda AWS Parameters and Secrets Lambda Extension timeout randomly

问题

我已设置一个 Python 3.10 Lambda，已附加 Secret Layer，并且未附加 VPC。

  • 超时时间为20秒
  • 执行通常需要1-3秒
  • 所有 Secret Layer 变量均未设置，因此使用默认设置

我注意到随机地（大约1次每10次），执行会超时。

大多数情况下，第一次执行会失败。

我已启用 PARAMETERS_SECRETS_EXTENSION_LOG_LEVEL 为 DEBUG 并在 CloudWatch 日志中检查：

通常在 DEBUG Caching secret with key /secretsmanager... 行之后，源代码会执行并且函数成功执行。
但在某些情况下，源代码甚至不会启动，因此我无法记录任何日志，因为它根本没有执行。

任何帮助都将受到欢迎，

编辑：
将超时时间增加到1分钟后，似乎对 Secret Manager 的请求速度太慢了。
问题在于 ApiGateway 超时时间为30秒，所以它会失败。

英文:

I have set up a Python 3.10 Lambda that has attached Secret Layer and NO VPC attached.

  • The timeout time is 20 seconds
  • The execution normally takes 1-3seconds
  • All Secret Layer variables aren't set, so the default

I have noticed that randomly (1 in ~10) the execution timeout.

It's mostly the first execution the one that fails.

I have enabled the PARAMETERS_SECRETS_EXTENSION_LOG_LEVEL to DEBUG and checked in CloudWatch logs:

Normally after the DEBUG Caching secret with key /secretsmanager... line, the source code is executed and the function succeds.
But in some cases the source code doesn't even start , so I can't write any logs inside because it doesn't get there

Any help is appreacited,

EDIT:
Increased time to 1m and looks like the request to secret manager is just too slow.
The problem is that ApiGateway timeouts at 30s, so it fails

经过许多故障排除后，发现问题的原因是源代码导致了超时。

对https://api.ipify.org的调用是罪魁祸首。

显然，这个API并不总是正常工作，随机花费1秒到大于1分钟的时间来回应IP。

英文:

So after much troubleshooting, found out that the reason was source code giving the timeout

A call to https://api.ipify.org was the culprit

Apparently the api isn't working all the time and randomly takes 1s to >1m to answer with the IP
