[evanchooly]

that lambda code attempts to poll the AWS infrastructure for incoming requests before proxying off the request to your lambda code. That's the unknown host (null) that it's complaining about. Dev mode is not currently supported for this extension. You'll need to run something like SAM local to approximate this.

[drissamri]

Alright, then this can be closed for now? Doing local validation with SAM Local works. Are there any plans to support this out of the box in the future?

[evanchooly]

I have a PR that rounds out the sam/local support. dev mode is slightly trickier...

[gsmet]

Reopening as it seems @evanchooly has something in the works on the subject.

[stefankurzbach]

In my setup the unit tests using LambdaClientsucceed because the quarkus-test-amazon-lambda module is running an integrated Undertow server (LambdaResourceManager) to poll against.

However several UnknownHostExceptionsare thrown by AmazonLambdaRecorderat the end of the tests, when shutting down the Undertow server. Can this behaviour be fixed too? It seems to be a matter of timing when a test extension is stopped and when the AmazonLambdaRecorderThread is shut down.

[jussiseppala]

So, it is impossible to run quarkus project in dev mode if it contains lambda function. Right?
How this can be solved? How can I run "mvnw compile quarkus:dev" when project contains lambda?

This issue/pullrequest has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[evanchooly]

This has been fixed in recent builds. 1.0.0-rc1 should be sufficient.
