What happened

我使用的是dbgpt 0.5.10版本, 当我上传文件到图知识库时发生报错{code: CypherException} {message: CypherException: visit(...) failed at src/cypher/arithmetic/ast_expr_evaluator.cpp:480} ，通过debug发现问题出现在app\dbgpt\storage\graph_store\factory.py文件中的return store_cls(config) 这一句，不知道是什么原因，请大佬们帮忙解答！ 试过txt和md格式文档，都会报错

What you expected to happen

希望老师们能够帮我找到原因，并解决，然后想问图知识库支持的是什么格式的文件来上传？

How to reproduce

1. 构建图知识库
2. 上传txt或md文件

hi,
could you show your .env Graph setting or try DB-GPT v0.6.1

@adogwangwang Hi, it seems like you have the same issue with #2079 (comment).
The good news it, we fixed it in v0.6.1. Therefore, please update db-gpt, and then update your env according to the .env.template, thank you.
