Packaging not working when deploying lambda function packaged using docker

[trobert2]

When deploying a PythonFunction using aws_lambda_python, the packaging takes place in a docker container. The packaging of the function, including automatic installation of the requirements.txt dependencies is done inside the container.

Locally the execution happens without any issues. Using the github actions this fails
workflow:

on:
  push:
    branches: [ main ]

jobs:
  aws_cdk:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: cdk diff
        uses: youyo/aws-cdk-github-actions@v2
        with:
          cdk_subcommand: 'diff'
          cdk_version: '2.9.0'
        env:
          AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
          AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          AWS_DEFAULT_REGION: 'eu-central-1'

Error AFTER installation from requirements.txt has taken place, states that requirements.txt is not present:

The CDK declaration is done like so (using __file__) to guarantee the location is always the same):

        handler_function = PythonFunction(
            self, "handlingFunction",
            entry=os.path.join(os.path.dirname(
                os.path.realpath(__file__)), "../src/lambda"),
            runtime=Runtime.PYTHON_3_9,
            index="lambda_function.py",
            environment={
                "LOGLEVEL": "DEBUG"
            },
            timeout=Duration.seconds(20),
            memory_size=512,
            tracing=Tracing.ACTIVE
        )

I know nodeJS functions can be bundled using esbuild but the python functions don't support local bundling.

I also encountered the same issue using the PythonFunction construct

Also for me same issue
