Is there possibility to setup forwarder to work with localstack?

HI. I want use your forwarder to work locally with a localstack. Is it possible?

My docker-compose env looks like this.

# This won't be used by CI/CD. This is just for local development

version: '3.8'

services:
  localstack:
    image: localstack/localstack-pro
    container_name: localstack
    networks:
      - internal-net
   ...

  rabbitmq-forwarder:
    image: airhelp/rabbit-amazon-forwarder:latest
    networks:
      - internal-net
    environment:
      AWS_REGION: eu-central-1
      MAPPING_FILE: /config/mapping.json
      AWS_ACCESS_KEY_ID: <MY_DUMMY_KEY_ID>
      AWS_SECRET_ACCESS_KEY: <MY_DUMMY_ACCESS_KEY>
      AWS_ENDPOINT_URL: http://localstack:4566
    depends_on:
      - rabbitmq
      - localstack
    volumes:
      - "./rabbitmq-forwarder/mapping.json:/config/mapping.json"

But when I send an event I've got the following error

{
    "error": "UnrecognizedClientException: The security token included in the request is invalid.\n\tstatus code: 403, request id: c9d1f1c4-7034-459e-9654-38b7d1639fed",
    "forwarderName": "test-lambda",
    "level": "error",
    "msg": "Could not forward message","time":"2023-12-07T07:47:20Z"
}

Thanks for all. Any help will be appreciated
Best regards.
