(aws-lambda-python-alpha): I'm failing to bundle a Python 3.12 function using pipenv.

[kamaD-y]

Describe the bug

When trying to export the Pipfile to requirements.txt, I encounter the following error:
AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?

Expected Behavior

I expect to successfully bundle.

Current Behavior

Traceback (most recent call last):

Reproduction Steps

I'm using the following stack.

import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import { aws_lambda as lambda } from 'aws-cdk-lib';
import { PythonFunction } from '@aws-cdk/aws-lambda-python-alpha';

export class TestStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);
    const entry = 'src'
    new PythonFunction(this, 'TestFunction', {
      functionName: "testFunction",
      runtime: lambda.Runtime.PYTHON_3_12,
      entry,
      index: 'index.py',
      handler: 'handler',
      bundling: {
        assetExcludes: ['.venv'],
      },
    });
  }
}

When I run cdk synth with the Pipfile placed in the src entry point, it results in an error.

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
requests = "*"

[dev-packages]

[requires]
python_version = "3.12"
python_full_version = "3.12.2"

Possible Solution

There is the following description in the Dockerfile.

# pipenv 2022.4.8 is the last version with Python 3.6 support
    pip install pipenv==2022.4.8 poetry==$POETRY_VERSION && \

I think it would be fine to upgrade the version of pipenv, as Python 3.6 is no longer supported by Lambda.
The same error was present up to pipenv==2023.3.20, but it seems that from pipenv==2023.4.20 onwards, the error does not occur

Unfortunately, I wasn't able to reproduce the issue on my machine using the provided snippets, both using CDK 2.141.0 and the current CDK 2.142.1. Using the provided stack and Pipfile, with Pipfile both under the src directory and the root directory, it synthesizes and deploys. Can you provide any additional details on how we can reproduce the issue?
