Error in AWS Lambda when sending custom events #1074
Description
Description
Hi, I'm using go-agent for New Relic and I'm encountering a sporadic error in some cases. The error is the following:
[NR_EXT] Telemetry client error: .... read: connection reset by peer
My Lambda function is executed multiple times, and at the end of the handler it sends a custom event to New Relic. The problem is that sometimes this custom event is skipped and not sent; instead, I get the error mentioned above.
What could be causing this? My Lambda has a generous timeout(15 seconds), so I don't think that's the reason.
Additionally, it's a Lambda that simply parses a JSON and sends it via SNS, so it doesn't contain any complex logic. As additional information, this Lambda is triggered by DynamoDB Streams. My Lambda follows the same example and timing as this one: https://github.com/newrelic/go-agent/blob/master/v3/examples/short-lived-process/main.go
Steps to Reproduce
I haven't been able to find the conditions to reproduce the error.
Expected Behavior
What I expect is that 100% of the events are sent, but approximately 1% don’t make it, and when I check the logs in CloudWatch, I find this error.
NR Diag results
In the CloudWatch logs, I see the error I mentioned earlier.
Your Environment
My environment is AWS, with a Lambda triggered by DynamoDB Streams. It's built in Go and, upon parsing a JSON, it performs a publish to SNS.
