kubernetes - ArangoDB 连接失败：到达流的末尾

Question

我在第一次设置简单的 arangodb 服务器时遇到了困难，因此我使用教程中的配置

apiVersion: "database.arangodb.com/v1alpha"
kind: "ArangoDeployment"
metadata:
  name: "arangodb"
spec:
  mode: Single

在客户端，我使用com.github.goodforgod:micronaut-arangodb捆绑arangodb-java-driver并将其集成到 micronaut 中。

连接设置也非常简单 ( application.yaml)

arangodb:
  hosts:
    - arangodb.default.svc:8529
  database: mydb
  user: myuser
  password: mypw

从客户端的日志中我明白了

所以在我看来，他能够打开一个套接字连接，但之后读取数据失败。服务器日志不包含任何内容。

所以我很迷茫如何处理这个问题？欢迎任何帮助问候奥利弗
