I am trying to clone a node in Neo4j using the APOC procedure apoc.refactor.cloneNodes. Although the node exists and the query executes without errors, the output is always null. I expect the output to contain the cloned node. Here’s the query I am using:

I have a query that dies after several hours because of memory consumption. I already addressed this question here: Neo4jError: db.memory.transaction.total.max threshold reached on AWS EC2 instance.

I am trying to insert a number of rows (more than 1 mil) from a CSV file into the graph database, the treasure table needs a relationship to a city, as in a treasure is found in ever city. I have created an index yet neo4j doesn’t seem to be using it:

I’m encountering an issue with my Neo4j database deployed on an AWS EC2 r6i.2xlarge (8 vCPU, 64GB of RAM) instance. Whenever I execute a specific Cypher query through my Node.js server using the neo4j-driver library (version 4.4.5), I receive the following error:

this is the error
Caused by: org.neo4j.driver.exceptions.ClientException: An equivalent constraint already exists, ‘Constraint( id=4, name=’constraint_b7299877′, type=’NODE PROPERTY EXISTENCE’, schema=(:profile {userName}) )’.

I have a xxx.db.dump file which is 1.7G big.

How to increase data returning speed on neo4j dashboard?

I am trying to connect to my Neo4j database, but I encountered an error. Could anyone assist me?I will be very grateful.

After executing this code to create a vctor index

When I used “:GET /rdf/neo4j/describe/358”, an error message of “Failed to fetch” returned. 358 is a returned ID(p) by a query of “MATCH (p:Product) WHERE p.productName = “Queso Manchego La Pastora””. How can I resolve it?
