Feature request: add Event Handler in Lambda layer

[Jan-PaulLangenfurth]

Expected Behavior

The event handler should be included with the lambda layer, V43 or 44

Current Behavior

Error when running the a Lambda with the with the version layer V43 OR 44.

Code snippet

import { Router } from '@aws-lambda-powertools/event-handler/http';
import type { Context } from 'aws-lambda';

const app = new Router();

app.get('/ping', async () => {
  return { message: 'pong' }; 
});

export const handler = async (event: unknown, context: Context) =>
  app.resolve(event, context);

Steps to Reproduce

1. create Lambda with powertools lambda layer V43/V44 in region eu-west-1
2. Test function
3. Function fails event hanlder is not included

Possible Solution

Add event handler to utilities when realsing a lambda layer:

const utilities = [

Hi @Jan-PaulLangenfurth, thanks for opening the issue.

This is not a bug but it's intentional - we haven't added the module to the Lambda layer yet (source).

I'm going to convert this in a feature request and we'll try to pick this up before the next release.
