i got this problem when i try to merge relationship for >10 nodes. It only works if it is below nodes to merge relationships for.
Neo.ClientError.Procedure.ProcedureCallFailed: Failed to invoke procedure
apoc.merge.relationship: Caused by: java.lang.NullPointerException
I searched and notice other ppl had similar problem but with other APOC procedure, however there seems to be no solution.
i did tried to set config such as apoc.import.file.enabled=true etc. but no use.
would appreciate if anyone could suggest a fix? thx
