django, postgresql consists of docker-compose, and sentry consists each as a container while looking at the official document. Then, I created a new network (my_network) and connected django and sentry. However, issue tracking does not work.

ps) It worked when django was turned locally instead of as a container.

version: '3.8'

volumes:
  postgres:
    driver: local
  redis:
    driver: local

services:
  postgresql:
    image: postgres
    # build: ./.docker/postgresql
    volumes:
      - postgres:/var/lib/postgresql/data/
    environment:
      POSTGRES_DB: aio_setting
      POSTGRES_USER: root
      POSTGRES_PASSWORD: aio0706!
    restart: unless-stopped
    ports:
      - '5432:5432'

  redis:
    # image: redis/redis-stack-server:latest
    image: "redis:alpine"
    restart: unless-stopped
    ports:
      - '6379:6379'
    volumes:
      - redis:/data

  app:
    build: .
    container_name: app
    command: /entrypoint.sh
    volumes:
      - .:/usr/src/app
    restart: unless-stopped
    ports:
      - "8000:8000"
    depends_on:
      - postgresql
      - redis

Do I need to specify a specific network

import sentry_sdk
from sentry_sdk.integrations.django import DjangoIntegration

sentry_sdk.init(
    dsn="http://e09d532f1c594fcebfa2bc51bcb7cfe6@my_network:my-sentry:8080/2",
    integrations=[DjangoIntegration()]
)

I want it to be an issue tracking
