Error encountered while trying to connect Neo4j using Talend tNeo4jInp

[Anonymous]

Trying to connect Neo4j from Talend to export a subset of data out of it based on the Cypher query passed as an parameter using tNeo4jInput api. During this process when I invoke the Talend job it fails with the below error logs.
Exception in component tNeo4jInput_1

Any help to make this connection work will be much appreciated.

Hi Ranjan,
 
Could you please show us the component setting screenshot of tNeo4jInput? What does your input subset of data look like?
 
 
Best regards
