Error in gds.graph.export (java.lang.IllegalStateException)

Neo4j Graph Platform
1

Hi,

I'm not being able to export my graph: as I try I get this error:"

Failed to invoke procedure `gds.graph.export`: Caused by: java.lang.IllegalStateException: This cursor is closed

Can you help me please?

Thanks,

RFaria

Hi, again. What version of GDS and Neo4j are you using? And how are you running/deploying Neo4j (server desktop, etc)?

Is this related to your other thread here? If you could provide a quick code snippet/example of what you are doing to produce this error it would help. Thank you.

Hi Zach, Thank you for your quick feedback.

I am using Neo4j desktop and please do find a snipet and code of what I'm doing.

//1. gds project.cypher

call gds.graph.project.cypher('service_similarity_graph',

'match (n) where n:servico\_tv or n:canal return id(n) as id',

'match (s:servico\_tv)-->(p:programa)-->(c:canal) return id(s) as source, id(c) as target')

// 2. node similarity

call gds.nodeSimilarity.mutate('service_similarity_graph',{mutateRelationshipType:'Similar',mutateProperty:'score',topK:10,similarityCutoff:0.25})

// 3 . louvain stream

call gds.louvain.stream('service_similarity_graph',{relationshipTypes:['Similar'],relationshipWeightProperty:'score'}) yield nodeId,communityId

return communityId, count(nodeId) as size order by size desc

// 4. louvain mutate

call gds.louvain.mutate('service_similarity_graph',{relationshipTypes: ['Similar'],relationshipWeightProperty:'score',mutateProperty:'louvaincommunity_new'})

// 5. write mutated result back

call gds.graph.writeNodeProperties('service_similarity_graph',['louvaincommunity_new'])

// 6. export graph to data base

call gds.graph.export('service_similarity_graph',{dbName:'servicesimilarity'})

In this last stpe I get the error than I've told before.

The error in the other thread is taken care of :slightly_smiling_face:
