What you expected to happen

正常创建知识库，并正常同步

How to reproduce

在创建知识库的时候，没有create知识库，就进行了连接导致出错。
TuGraph 正常启动
以下是.env配置：

##
#** VECTOR STORE / KNOWLEDGE GRAPH SETTINGS **#
##
VECTOR_STORE_TYPE=Chroma
GRAPH_STORE_TYPE=TuGraph
GRAPH_COMMUNITY_SUMMARY_ENABLED=True
KNOWLEDGE_GRAPH_EXTRACT_SEARCH_TOP_SIZE=5
KNOWLEDGE_GRAPH_EXTRACT_SEARCH_RECALL_SCORE=0.3
KNOWLEDGE_GRAPH_COMMUNITY_SEARCH_TOP_SIZE=20
KNOWLEDGE_GRAPH_COMMUNITY_SEARCH_RECALL_SCORE=0.0

Chroma vector db config

CHROMA_PERSIST_PATH=/root/DB-GPT/pilot/data

TuGraph config

TUGRAPH_HOST=192.168.1.102
TUGRAPH_PORT=7687
TUGRAPH_USERNAME=admin
TUGRAPH_PASSWORD=73@TuGraph
TUGRAPH_VERTEX_TYPE=entity
TUGRAPH_EDGE_TYPE=relation
TUGRAPH_PLUGIN_NAMES=leiden

#开启图社区总结能力
GRAPH_COMMUNITY_SUMMARY_ENABLED=True

我发现代码在call createLabel的时候出现错误！
创建标签的时候，数据类型缺少引号
正确的：
CALL db.createLabel('vertex', 'new_label', 'id', ['id','int32',false], ['name','string', true]);
错误的：
CALL db.createLabel('vertex', 'new_label', 'id', ['id',int32,false], ['name',string, true]);

试了下确实是这样，把参数里的类型用引号引起来就能跑通了

通过Web UI 添加知识库也存在同样的问题，应该是bug

没错，确实是这样，修改路径：dbgpt\storage\graph_store\tugraph_store.py
修改如下：

这个怎么解决呢？
