在ArangoDB中插入或更新文档失败，违反了约束

我希望在ArangoDB中实现一个Upsert，但我无法使用的文档中提供的示例来实现它。我的请求失败，并显示违反了

唯一约束的
错误消息

我在集合中插入带有特定
\u键的文档，并且
覆盖
选项设置为
真
，如文档中所述，但仍会收到错误消息。下面是在我的环境中所描述的curl调用的结果

呼叫#1:

curl -X POST --header 'accept: application/json'\
             --data-binary @- --dump - \
             http://localhost:8529/_api/document/products\?overwrite\=true \

呼叫#2:（识别第一个）

我浏览了文档，启用并查看了服务器日志，但我无法理解。任何帮助都将不胜感激

以防万一，如果这有什么帮助的话，我使用Docker在本地运行ArangoDB服务器，并使用以下Docker组件

version: '3'
services:
  db:
    image: arangodb
    ports:
    - "8529:8529"
    environment:
      ARANGO_NO_AUTH: 1
    volumes:
      - ./arangodb3:/var/lib/arangodb3
    command: "--log.level startup=trace --log.level requests=trace --log.level info"

这是服务器的日志：

我在ArangoDB社区的slack频道上发布了这个问题，那里的优秀人士向我指出，通过overwrite参数的replace insert是在
3.4
中才引入的。根据我的docker compose，我的图像指向arangodb的最新图像，即
3.3.20

我被解释说，这个“官方”存储库（
arangodb
）不一定托管最新的稳定版本的arangodb，而且它可能需要几天才能可用，我应该指出
arangodb/arangodb

我修改了我的
docker compose.yml
文件以使用正确的图像，现在它工作正常

docker compose.yml:

curl -X POST --header 'accept: application/json'\
             --data-binary @- --dump - \
             http://localhost:8529/_api/document/products\?overwrite\=true \

再次感谢ArangoDB社区的Slack，尤其是@mpoter
 作为参考，在编写docker拉取的ArangoDB版本时，作为
最新版本
是
3.3.20
。您可以接受您的答案，以表明问题已解决。谢谢
