[NodeJS] Cannot use node inspector, port in use

[abhinav-enboarder]

I am trying to run the Node 22 image on my local and want to start the process with inspect flag, for doing so I passed the env var NODE_OPTIONS but on container startup I get an error that the port specified is in use.

Docker compose:

my-service:
    build: ../backend/my-service
    depends_on:
      - db
    restart: always
    container_name: my-service
    ports:
      - "6012:5001"
    environment:
      NODE_OPTIONS: "--inspect=0.0.0.0:5001"

Dockerfile:

FROM public.ecr.aws/lambda/nodejs:22

COPY . /var/task/
WORKDIR /var/task/

CMD [ "my-service.lambda.handler" ]

Container logs

Debugger listening on ws://0.0.0.0:5001/cb34b78e-0c31-4521-babf-1f3f28589426
For help, see: [https://nodejs.org/en/docs/inspector⁠](https://nodejs.org/en/docs/inspector)

Exec inside container

The problem persists even when I change ports (I have tried a lot of them)
