APOC - apoc.path.expandConfig - Procedure Not found

Neo4j Graph Platform Cypher
1

Hi Team,

I have apoc plugins - apoc-3.5.0.1-all.jar in neo4j DB. But when i run below Cypher query getting below error

match(n {path:'/PROJECTS/DATA/SERIAL/MORT/PUB_MORT_SVCG/ARCH/CAPDW_FW_LPS_MONTHLY_2520'})
with (n)
call apoc.path.expandConfig(n,{relationshipFilter: "TO",
labelFilter: "",
uniqueness: "",
minLevel:1, maxLevel:5,
filterStartNode:false}) yield path as path
return path
Limit 100;

Neo.ClientError.Procedure.ProcedureNotFound: There is no procedure with the name apoc.path.expandConfig registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.

I've not used expandConfig, but it can be replaced for your query ?

MATCH p=(n)-[*..5]-() WHERE n.path='/PROJECTS/DATA/SERIAL/MORT/PUB_MORT_SVCG/ARCH/CAPDW_FW_LPS_MONTHLY_2520'
RETURN p LIMIT 100

This is working fine.. I need to skip any nodes.. need to use apoc expand config in label filter. So that will have leverage to skip nodes in between.

But if apoc.path.expandConfig is missing means - I missed something during neo4j installation?

The jar should be in the plugins folder. Where did you download the jar from, and what version of Neo4j are you using with this?

I've tried with MovieGraph data and apoc.path.expandConfig works..
Neo4j Desktop 1.1.15 + Neo4j 3.5.2 + APOC 3.5.01

MATCH (n:Person) WHERE n.name='Tom Hanks'
WITH n
CALL apoc.path.expandConfig(n, {relationshipFilter: "ACTED_IN", labelFilter: "", uniqueness: "", minLevel: 1, maxLevel: 5, filterStartNode: false}) yield path
RETURN path
LIMIT 3

Like this i need to add anything in neo4j.conf

dbms.security.procedures.unrestricted=apoc.trigger.,apoc.meta.

Can you please check your neo4j.conf and let me know? it will be very helpful

Thanks,
Nithin.

yea .. I have inside apoc jar file inside plugins folder. Neo4j 3.5

My config is like this. It may helps.

dbms.security.procedures.unrestricted=apoc.*
10

It didn't help after adding in config file :expressionless:

I have noticed jar file doesn't have full rights.. Once i gave full rights.. issue resolved

Thanks,
Nithin.
