Response Transformer - Error TypeError: Cannot read property "MSA.1" from undefined

[newbie_mrth]

Hi all,

I want to add a filter so that only AE type messages are routed to my response channel but I seem to be getting error "TypeError: Cannot read property "MSA.1" from undefined"

Anyone know why it's failing?

var AckResponsePro = globalChannelMap.get('AckResponseProcessor');
var hl7Response = SerializerFactory.getSerializer('HL7V2').fromXML(t mp);


var msa1 = hl7Response['MSA']['MSA.1']['MSA.1.1'].toString();

if (msa1 == 'AE') {

router.routeMessage(AckResponsePro, hl7Response);

} else {

return false;

}

Ah it was a simple change and is now working as expected! Changed hl7Response to tmp!
