我正在使用docker-compose来编排两个服务，但是其中一个服务出现了错误。根据日志，下面是我的输出：

我还没有尝试任何解决方案，因为我不知道从哪里开始。我该如何解决这个问题？

重现步骤：

1.在干净的Ubuntu 22.04LTS服务器上，安装了docker和docker-compose。
1.为服务创建了一个目录，并对docker-compose.yml使用了以下配置：

version: '3'

services:
  server:
    image: registry.gitlab.com/commento/commento:SET_VERSION
    ports:
      - 8080:8080
    environment:
      COMMENTO_ORIGIN: http://commento.example.com:8080
      COMMENTO_PORT: 8080
      COMMENTO_POSTGRES: postgres://postgres:postgres@db:5432/commento?sslmode=disable
    depends_on:
      - db
  db:
    image: postgres
    environment:
      POSTGRES_DB: commento
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
    volumes:
      - postgres_data_volume:/var/lib/postgresql/data

volumes:
  postgres_data_volume:

1.运行docker-compose up -d，然后我跟踪了两个服务的日志，服务“commonto_server_1”产生了上面提到的输出。
