I'm using Elastic APM on my .NET 6 API which works perfectly fine.
I'm trying to get it roll on my console and AWS Lamdba deploys as well.
I moved out the important pieces to a separate project to easier debug and show my setup here; [https://github.com/privjimmie/ApmDebug](https://github.com/privjimmie/ApmDebug)
The bottom line is that I can't figure out how to get the APM transactions to be sent out / flushed before the app is shutdown.
```auto
warn: Elastic.Apm[0] {PayloadSenderV2} Cancellation requested. Following events were not transferred successfully to the server xxx
```
(Full log below)
**Kibana version** : 8.4.3

**APM Agent language and version** : Elastic.Apm.NetCoreAll v 1.18.0
**Provide logs and/or server output (if relevant)**:

How can I flush the transactions to elastic apm server before shutting down the app?

Hi @jimmie,
this is a known limitation - we plan to address this in a future release.
Here is a GitHub issue about it: [Agent API to flush all the queued events · Issue #288 · elastic/apm-agent-dotnet · GitHub](https://github.com/elastic/apm-agent-dotnet/issues/288) (there are some other related issues - including ones specifically for lambda - as well in the repo; but this comes down to the missing feature and the linked issue).

Oh, okey. I thought it was me missing something. Thanks for the quick feedback @GregKalapos
