Cannot pass sucessifuly through healthcheck with lsof

Question

I've tried to up a docker-compose with three services, but it fails on healthcheck.

It is made by searching a specific running port with lsof: test: ["CMD", "lsof", "-t", "-i:3001"]

Nevertheless, when I try to reach the service by that specific port, binded on the docker-compose, it works seamslessly to me.

I've tried to run this command with running container, and this did not work too. So I realized that I should run it with sudo, and, by this way, it returns a sucessfully response (0).

I was looking for use the sudo command and I've found that the Docker Daemon runs on root mode. So it break out my theory.

Someone has some ideia about what can be making my healthcheck don't be sucessfully?

Follow the code:

version: '3.9'

services:
  frontend:
    container_name: front-end
    build: ./src/front-end
    ports:
      - 3000:3000
    restart: on-failure
    networks:
      - frontend
    healthcheck:
      test: ["CMD", "lsof", "-t", "-i:3000"]
      interval: 10s
      timeout: 5s
      retries: 5
    depends_on:
      backend:
        condition: service_healthy
        

  backend:
    container_name: back-end
    build: ./src/back-end
    working_dir: /backend
    environment:
      - BACKEND_PORT=3001
    ports:
      - 3001:3001
    restart: on-failure
    networks:
      - frontend
      - backend
    healthcheck:
      test: ["CMD", "lsof", "-t", "-i:3001"]
      interval: 10s
      timeout: 5s
      retries: 5
    depends_on:
      database:
        condition: service_healthy
  
  database:
    container_name: database
    image: mongo:6.0.4
    ports:
      - 27017:27017
    environment:
      MONGO_INITDB_ROOT_USERNAME: ${ECONDOS_MONGODB_USER}
      MONGO_INITDB_ROOT_PASSWORD: ${ECONDOS_MONGODB_PASSWORD}
    networks:
      - backend
    healthcheck:
      test: ["CMD", "mongosh", "--eval", "db.runCommand({ ping: 1 })", "--quiet"]
      interval: 10s
      timeout: 5s
      retries: 5

  frontend:
  backend:
