docker - Docker撰写-services.vulcain.ports包含无效的类型，应为数字或对象

Question

我正在使用Symfony和docker，并且相信我在设置这两个时出错，这使我在docker compose中遇到了这个错误:services.vulcain.ports contains an invalid type, it should be a number, or an object在运行docker compose命令时:dc exec php vendor/bin/simple-phpunit --filter 'App\\Tests\\EntityTests::testName'我会精确说明我的文件夹体系结构可能是问题所在:
我有一个/project文件夹，它是项目的路线
其中有两个文件夹/frontend和/backend，再加上此脚本可以前后启动:

#!/bin/bash

docker-compose -f backend/docker-compose.yml up -d ; 
docker-compose -f frontend/docker-compose.yml up -d ;

/frontend与我无关，我从 /api fodler启动了命令
其中自己包含 /docker(带有dockerfile)和 /api文件夹以及我的docker-compose。
我的 docker-compose来自api平台文档:

version: '3.4'

  - &api-cache-from

    networks:
      - symfony

volumes:
  db-data: {}
  dev-certs: {}

networks:
  symfony:
    driver: bridge

和错误:

ERROR: The Compose file './../docker-compose.yml' is invalid because:
services.db.ports contains an invalid type, it should be a number, or an object
services.mercure.ports contains an invalid type, it should be a number, or an object
services.vulcain.ports contains an invalid type, it should be a number, or an object

来源于我精确调整docker-compose中的端口的方式，因为它们来自位于 /backend文件夹中的.env文件，并且我正在执行comand并位于 /api文件夹中的下一个文件夹。
但是，如果我从 /backend执行相同的命令，则会收到以下消息:

Time: 115 ms, Memory: 6.00 MB

No tests executed!

任何人都不知道该如何解决？

当您触发“docker-compose up”时，您可能还会收到以下警告:

kalou@shinwey:~/t$ docker-compose  up
WARNING: The VULC_TARGET variable is not set. Defaulting to a blank string.
WARNING: The VULC_PUBLISHED variable is not set. Defaulting to a blank string.
WARNING: The DB_TARGET variable is not set. Defaulting to a blank string.
WARNING: The DB_PUBLISHED variable is not set. Defaulting to a blank string.
WARNING: The MERC_TARGET variable is not set. Defaulting to a blank string.
WARNING: The MERC_PUBLISHED variable is not set. Defaulting to a blank string.
ERROR: The Compose file './docker-compose.yml' is invalid because:

services.mercure.ports contains an invalid type, it should be a number, or an object
services.vulcain.ports contains an invalid type, it should be a number, or an object

必须在“docker-compose up”命令之前设置这6个变量。
