Serverless localstack plugin does not autostart docker container

Hey there, I have a strange behaviour with the plugin when using it with the docker flag autostart: true. The situation is that our config works on my machine, but it does not work on the machine from a colleague. It starts a localstack container as expected, but on the other machine, nothing is happening. I tried to debug it a couple of times, but did not get any further. Do you have any idea what is going wrong here?

service: akeneo-graphQL-connector

plugins:
  - serverless-localstack
  - serverless-plugin-typescript

provider:
  name: aws
  stage: local
  region: eu-central-1
  runtime: nodejs20.x
  stackName: akeneo-graphQL-connector
  environment:
    DYNAMODB_TABLE: "test"
  iamRoleStatements:
    - Effect: Allow
      Action:
        - dynamodb:Query
      Resource: "arn:aws:dynamodb:${opt:region, self:provider.region}:*:table/${self:provider.environment.DYNAMODB_TABLE}"

custom:
  localstack:
    stages:
      # list of stages for which the plugin should be enabled
      - local
    host: http://localhost  # optional - LocalStack host to connect to
    edgePort: 4566  # optional - LocalStack edge port to connect to
    autostart: true  # optional - Start LocalStack in Docker on Serverless deploy
    lambda:
      # Enable this flag to improve performance
      mountCode: True
    docker:
      # Enable this flag to run "docker ..." commands as sudo
      sudo: False

functions:
  akeneo-graphQl:
    handler: handler.akeneoGraphQLInteractor
    name: akeneo-graphQl-connector-api
    description: A microservice for connection to the akeneo Graph QL pim and related akeneo Graph QL api executions
    timeout: 300
    events:
      - http:
          path: /{proxy+}
          method: any
          cors: true

We both start our local development with npm run start-local-dev

Our scripts to run the localstack plugin with nodemon

  "scripts": {
    "build": "npx tsc",
    "deploy": "LAMBDA_REMOVE_CONTAINERS=1 LAMBDA_KEEPALIVE_MS=5 serverless deploy --stage local",
    "watch": "npx nodemon -e '.ts' -x 'npm run build' || exit 1",
    "start-local-dev": "LAMBDA_REMOVE_CONTAINERS=1 LAMBDA_KEEPALIVE_MS=5 npm run deploy && npm run watch",
  }

The versions we are using:

    "nodemon": "^3.1.0",
    "serverless-localstack": "^1.2.1",
    "serverless-plugin-typescript": "^2.1.5",

serverless is used in 3.39.0. We tried to install it with npm install -g serverless@3.39.0 or with homebrew brew install serverless docker is also usable via the cli with the current user, so no root rights needed for that.

Do you have any idea why it works with these commands on my machine, but does not on the machine of my colleague?

This is his output after the start npm run start-local-dev


akeneo-connector@1.0.0 start-local-dev

> akeneo-connector@1.0.0 deploy
