Unable to start application with docker-compose on a new project due to invalid app.yml

Overview of the issue

I tried to run the docker image following the instructions here on a newly created jhipster nodejs project https://www.jhipster.tech/docker-compose/

16:25 ~/src/energy-manager (integration) $ docker-compose -f src/main/docker/app.yml up ERROR: The Compose file './src/main/docker/app.yml' is invalid because: services.energymanager-app.environment contains an invalid type, it should be an object, or an array services.energymanager-app.ports is invalid: Invalid port "{'8081:8081': None}", should be [[remote_ip:]remote_port[-remote_port]:]port[/protocol] services.energymanager-app.ports contains an invalid type, it should be a string, or a number

Here is my energy-manager/src/main/docker/app.yml version: '2' services: energymanager-app: build: ../../.. container_name: energymanager-app environment: ports:

8081:8081:

Motivation for or Use Case

The docker compose command should work out of the box
