JumpCloud Serverlesss Lambda Function timeout error

Question

Hello Giks,

Hope all doing good.
I'm facing issue while running a serverless application Lambda function. I used this application to download files from remote node and store it to S3 bucket. it was working fine previously, all of sudden it stop fetching files source location. while debugging issue I observe that it was a lot of time complete a test event. In the CloudWatch logs I'm getting below error logs.

I have tried increasing memory and timeout parameter but still getting same error. 
In X-Ray Trace Logs getting below response.

Can anyone advise if anything I missed to debug.

Accepted Answer

If something is suddenly taking three minutes to complete (when it didn't before) and there is a "remote node" involve I would suspect something network-wise as the problem. DNS. Reachability. Firewalls at the far end. Something.

I'm something of a Luddite here but if it were me I'd be putting debug statements with timestamps at every step of the way within the code and figuring out what is going on. Brute force: yes. Elegant: no. Good at figuring out the problem? Absolutely.

Answer

As you can see in the logs you shared, the Lambda functioned timed out: `Task timed out after 180.63 seconds`.

I don't have enough information to tell you why it did. Good news is that there is a [troubleshooting guide](https://aws.amazon.com/premiumsupport/knowledge-center/lambda-troubleshoot-invocation-timeouts/) which you can use to identify the issue and then fix it.

Hope this helps.
