@vritser Thanks so much for your PR.

Issue: when GraphRAG builds the DB schema, different versions of TuGraph handle the types STRING and "STRING" differently (one version supports STRING; while the other version supports "STRING"). It is caused by the TuGraph version update.

We fixed it in another PR (document structure search in GraphRAG), and will release it in the next released version of DB-GPT.

Solutions: We used statements createVertexLabelByJson and createEdgeLabelByJson to be compatible with the new and old versions of feat. (note: createVertexLabelByJson and createEdgeLabelByJson have not yet been updated in the official documentation of TuGraph)

            gql_data = json.dumps({
                "label": graph_elem_type.value,
                "type": "EDGE",
                "constraints": edge_direction(graph_elem_type),
                "properties": graph_properties,
            })
            gql = f"""CALL db.createEdgeLabelByJson('{data}')"""
