Hi Team,

I got the below error in in-consistency reports of my Neo4j DB.

Can anyone help me out in telling what is this issue and how to solve it and what is the impact of this error ??

What Neo4j version? nd Edition?

If this is Neo4j 4.x? ??? and Enterprise edition then you can use neo4j-admin copy to prune out the inconsistency. Copy a database store - Operations Manual

See GitHub - jexp/store-utils: Utilities to compact, copy, fix, analyse Neo4j stores for a 3.5 equivalent and this was the predecessor to neo4j-admin copy and can be used where neo4j-admin copy is not available. An to which this is a offline process to read a graph.db and remove any/all inconsistencies

It should be noted and whereas Neo4j 3.5.0 was released November 2018 ( Neo4j 3.5.0 - Neo4j Graph Data Platform ) it is coming off patch support in 1 month, May 2022 and as such no further patches will be released for 3.5. So it would be in your best interest to upgrade
