Lambda: SnapStart Warning

[jrobbins-LiveData]

Describe the issue

In trying out the new Python SnapStart feature, I see this warning

[Warning at /LambdaFunction] SnapStart only support published Lambda versions. Ignore if function already have published versions [ack: @aws-cdk/aws-lambda:snapStartRequirePublish]

Since apparently the only way I can enable SnapStart is on the Function construct (and not on the VersionOptions construct), it seems that "doing it right" with CDK entails getting this spurious warning?

Also, the grammar of the warning seems a bit wrong: It would be better phrased as SnapStart only supports published Lambda versions. Ignore if function already has published versions.

This isn't technically a documentation issue, but, rather, a CDK deploy-time output issue, but since there's a grammar component, I thought maybe it belonged here.

Yes we should fix the grammar error. We welcome the PRs.

To dismiss this warning, you can use cdk acknowledge for that.

Thanks @pahud. Is there a "HOWTO" doc I could read to learn how to create the PR?

To dismiss this warning, you can use cdk acknowledge for that.

I may be missing something but if I run npx cdk acknowledge @aws-cdk/aws-lambda:snapStartRequirePublish I end up with a null in the cdk.context.json acknowledged-issue-numbers property and the warning persists.

I instead had to add the following acknowledgement in my cdk code:

    cdk.Annotations.of(func).acknowledgeWarning(
      '@aws-cdk/aws-lambda:snapStartRequirePublish',
    );
