Hi I am getting the following error while inserting into the entrypoint.

rule "Check if EligibleAlert is an Signature Event"
agenda-group "enrichment"
auto-focus true

no-loop true
when
    $list : EventSignatureList();
    $p : EligibleAlert($a : alert, $a.eventSignatureProcessingStatus!="TRUE" );
    eval((ifMatchesSyslog($list.getAllSyslogMnemonics(), $a)!=null) )

then
        try{
                WorkingMemoryEntryPoint eventsignaturestream = drools.getEntryPoint("EVENT SIGNATURE STREAM") ;
                eventsignaturestream.insert($p);
                } catch(Exception e)
        {
            log.error("[EventSignatureRules] - exception in Check if EligibleAlert is an Signature Event alert[ids=" + $p.getAlert().getId() + "][error:" + e.toString() + "]");
        }
end

And I am creating the session this way:

        knowledgeBaseConfig = KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
        knowledgeBaseConfig.setOption( EventProcessingOption.STREAM );
        kBase = KnowledgeBaseFactory.newKnowledgeBase( knowledgeBaseConfig );


        kBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages());


        KnowledgeSessionConfiguration knowledgeSessionConfig = KnowledgeBaseFactory.newKnowledgeSessionConfiguration();
        ((SessionConfiguration) knowledgeSessionConfig).setClockType( ClockType.REALTIME_CLOCK );
        kBase.newStatefulKnowledgeSession(knowledgeSessionConfig,null);

I get the Following error when my rule fires:
