I am using devcontainers for a project in vscode with WSL, since yesterday I got an error that doesn’t let met to start the devcontainers.

The error in log shows that when trying to get the content of file product.json:

[2024-05-04T04:45:06.972Z] Start: Run in container: cat '/home/vscode/.vscode-server/bin/b58957e67ee1e712cebf466b995adf4c5307b2bd/product.json'

The file ‘product.json’ in container is empty which is causing the error
In docker-compose.yml file i have the devcontainers, PostgreSQL, and rabbitmq services:

version: '3'
services:
  backend:
    container_name: backend
    image: mcr.microsoft.com/devcontainers/python:1-3.9-bullseye
    volumes:
      - .:/workspace:cached
    # Other configuration options for the Python container
    command: sleep infinity
    links:
      - frontend
    environment:
      - TZ=Etc/GMT-5
    networks:
      - mnet

  frontend:
    container_name: frontend
    image: mcr.microsoft.com/devcontainers/typescript-node:0-14
    volumes:
      - .:/workspace:cached
    # Other configuration options for the TypeScript container
    command: sleep infinity
    environment:

    networks:

  postgres-db:
    container_name: postgres-db
    image: postgres:16
    volumes:
      - db-data:/var/lib/postgresql/data
    environment:
      - POSTGRES_USER=dbuser
      - POSTGRES_PASSWORD=dbpwd
      - POSTGRES_DB=mydb
    networks:
      - mnet
    ports:
      - 5432:5432
  rabbitmq:
    container_name: rabbitmq
    image: rabbitmq:3.9
    volumes:
      - rabbitmq-data:/var/lib/rabbitmq
    environment:
      - RABBITMQ_DEFAULT_USER=radmin
      - RABBITMQ_DEFAULT_PASS=rpassword
    ports:
      - 5672:5672
      - 15672:15672
    networks:
      - mnet

volumes:
  db-data:
  rabbitmq-data:

networks:
  mnet:
    driver: bridge

There is a folder called .devcontainer and inside there is two folders, one called backcontainer which has the devcontainer.json file, the same with the other folder called frontcontainer.

backcontainer/devcontainer.json

{
    "name": "Backend",
    "dockerComposeFile": ["../../docker-compose.yml"],
    "service": "backend",
    "shutdownAction": "none",
    "workspaceFolder": "/workspace/backend"
}

frontcontainer/devcontainer.json

{
    "name": "Frontend",
    "dockerComposeFile": ["../../docker-compose.yml"],
    "service": "frontend",
    "shutdownAction": "none",
    "workspaceFolder": "/workspace/frontend"
}

I tried rebuilding the containers backend and frontend ,also deleting that containers but i got the same result.

I have another project with devcontainers and is working fine, but in this case i don’t know what else to modify.
