             Summary: SearchElasticsearch behaves differently to ScrollElasticsearchHttp, the processor it replaces
                 Key: NIFI-10304
                 URL: https://issues.apache.org/jira/browse/NIFI-10304
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.16.3
            Reporter: Vijaya Gorla


When GetElasticsearch processor has an incoming connection, and the document id is an expression, this results in expression evaluating to null when the processor runs without a flow file. This in turn results in elasticsearch GET api being invoked without an ID and elastic throwing an error.

Also noticed that other processors handle this scenario by short-circuiting at the beginning of onTrigger method

{code:java}
        FlowFile input = null;
        if (context.hasIncomingConnection()) {
            input = session.get();

            // If we have no FlowFile, and all incoming connections are self-loops then we can continue on.
            // However, if we have no FlowFile and we have connections coming from other Processors, then
            // we know that we should run only if we have a FlowFile.
            if (input == null && context.hasNonLoopConnection()) {
                return;
            }
        }
{code}

However GetElasticsearch  does not.
