Apoc.periodic.iterate() ClassNotFoundException

[acolbert]

Hi there, can someone please help me interpret this error code on apoc.periodic.iterate():

{code: Neo.ClientError.Procedure.ProcedureCallFailed} {message: Failed to invoke procedure apoc.periodic.iterate: Caused by: java.lang.ClassNotFoundException: org.threeten.bp.Duration}

the call is constructed like this:
CALL apoc.periodic.iterate( 'CALL apoc.load.jdbc($jdbc_url, "SELECT * FROM $my_db", [], {autoCommit:true}) YIELD row', 'MERGE (t:Thing {thing_id: row.thing_id}) SET t.thing_name = row.thing_name, t.created_at = row.created_at RETURN COUNT(*) AS total', { batchSize:$batch_size, parallel:true} ) YIELD total, timeTaken;

Thanks!

It simply means what it says.Above class library is not there on java classpath.
Many thanks

What version of Neo4j? version of APOC?

$jdbc_url? to which database vendor are you extracting data from and importing into Neo4j? I presume you have said database vendors jdbc driver jar file in plugins/ ?

is there a stacktrace recorded in the logs\debug.log at the time of error?

The problem was a missing .jar (threeten) for the JDBC driver plugins folder. Thank you both!
