Docker compose exporting ports is not working (according the docs)

I am working in a local docker image that I created.

Now I am using docker-compose to send more parameters.

version: '2'
services:
  helloworld:
    image: helloworld:1.0
    environment:
      ports:
        - "8002:8002"

so, according the docker documentation https://docs.docker.com/compose/compose-file/compose-file-v2/#ports is the right way to do it

But everytime I try to run it I get that 

services.helloworld.enviroment.ports contains ["8002"], which is an invalid type, it should be a string, number, or a null

I have tried removing the quotes, the - , different spaces and all have same results :s should be very simple but cannot figure it out, any idea?

Yaml files are white space sensitive. With your indentation, you've placed the ports within an environment section where it doesn't belong. Instead you need it within your service:

version: '2'
services:
  helloworld:
    image: helloworld:1.0
    ports:
    - "8002:8002"
