Apache AGE is a PostgreSQL extension that provides graph database functionality. AGE is an acronym for A Graph Extension, and is inspired by Bitnine’s fork of PostgreSQL 10, AgensGraph, which is a multi-model database. The goal of the project is to create single storage that can handle both relational and graph model data so that users can use standard ANSI SQL along with openCypher, the Graph query language. The data elements Apache AGE stores are nodes, edges connecting them, and attributes of nodes and edges.

Hi, i'm trying the examples but i got this error:

An error occurred: 1 validation error for GraphCypherQAChain
graph
Input should be an instance of GraphStore [type=is_instance_of, input_value=<langchain_community.grap...t at 0x000001D644EA71A0>, input_type=AGEGraph]
For further information visit https://errors.pydantic.dev/2.10/v/is_instance_of

And I have checked that AGEGraph is instance of GraphStore.

I am having the same error, I noticed langchain-neo4j has been updated recently. If you revert to version 0.1.0 it works. hope they will fix it with the latest version.

pip install langchain-neo4j==0.1.0
