### Question

I'm trying to implement locally DLQ for SNS with SQS, the problem is, on localstack SQS DLQ message coming from SNS have different format than what you would expect in AWS

When I tested locally I received the message in the following format:

`"{\"Action\": [\"Publish\"], \"Message\": [\"(The original SNS message body here)\"], \"TopicArn\": [\"the topic arn in localstack\"], \"Version\": [\"2010-03-31\"]}"`

I'm using local stack 0.14.0 with docker-compose

my docker-compose file looks like this:


```
 aws:
    image: localstack/localstack:0.14.0
    restart: always
    volumes:
      - ./docker-mounts/localstack:/docker-entrypoint-initaws.d
    environment:
      - SERVICES=sqs,s3,ses,sns
      - DEFAULT_REGION=eu-west-1
      - HOSTNAME_EXTERNAL=aws.localtest.local
      - AWS_ACCESS_KEY_ID=foo
      - AWS_SECRET_ACCESS_KEY=bar
      - AWS_DEFAULT_REGION=eu-west-1
```
