Cannot use the "latest" keyword for Sentry Lambda layer in serverless files.

[codebravotech]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Self-hosted/on-premise

Which SDK are you using?

@sentry/node

SDK Version

7.110.0

Framework Version

Link to Sentry event

No response

SDK Setup

No response

Steps to Reproduce

Attempt to add "latest" keyword to the Sentry lambda layer arn.

Per the Sentry dev team's request, this is a new/duplicate issue for a previous request that has gone stale: #3834

It would be really helpful to be able to use the "latest" keyword when adding the Sentry lambda layer to serverless framework configuration files, which requires the ListLayerVersion IAM permission.

Expected Result

Sentry can pull the latest version.

Actual Result

Sentry throws an error using that version. Needs the ListLayerVersion IAM permission.

We're busy working on our major version #9508 at the moment, so backlogging for now.

@andreiborza do you know if this is still an issue? I lack the context on it atm.

[andreiborza]

@AbhiPrasad I believe so. I opened up a PR in craft where I think it needs to be defined in.

We had to revert this change as it broke publishing. Will investigate further.

Ok, after investigating further, the lambda:ListLayerVersions policy unfortunately only works within the same AWS account that publishes the layers. There's no cross-account way of fetching a list of layer versions.

I know this won't help with serverless, but you could fetch the latest version from our release registry: https://release-registry.services.sentry.io/aws-lambda-layers
