What happened

依照 GraphRAG 运行时，在创建 Entity 期间报错：

我看了 https://github.com/eosphoros-ai/DB-GPT/issues/2019 ，简单改了代码生效。

但是总觉得事情没那么简单。这么低级的错 dev 不可能犯，怀疑是 tugraph-server 配置不匹配。

请问 GraphRAG 功能，对 tugraph 版本/配置有什么要求？

What you expected to happen

正常运行 tugraph 建表和查询。

How to reproduce

按照 https://www.yuque.com/eosphoros/dbgpt-docs/uskmaanno5ezcixv 教程执行就会有。
