Neo4j社区版不能创建新的数据库，只能有一个默认的数据库。

Facing the same

[Jeremy4455]

Facing the same, it leads to "Sorry, I'm not able to provide an answer to that question.[no-context]", because lightrag cannot retrieve the data in the neo4j and cannot ask the query

Same but I was running into:

This Neo4j instance does not support creating databases. Try to use Neo4j Desktop/Enterprise version or DozerDB instead. Fallback to use the default database.

When i have a neo4j container running and have tested it with other graphs and that works

As a workaround, you can put this part of code into yours. Then LightRAG will use the default database.

os.environ["NEO4J_DATABASE"] = "neo4j"

you can change the config of neo4j . set initial.dbms.default_database to chunk-entity-relation
