Default ERROR MESSAGE: Error evaluating transformer

I'm going through the book "Unofficial Mirth Connect 3.1 Developer's Guide" and I'm at chapter 5 "Query Sender Channel".

I've created the Query Sender channel, inbound and outbound datatypes are HL7 v2.x. Source Connector Type is Channel Reader, destination Connector Type is File writer. I test write and successfully connect to my path.

When I deploy the channel and send an HL7 message it successfully writes to the file. The problem is when I use the destination transformer and add the steps that the book says to add. I get an error when I try to send a message.

I add 4 steps and they are:

Name: MSH Segment
Type: JavaScript
Script:
Code:
tmp = msg;
tmp['MSH']['MSH.7']['MSH.7.1'] = Now("yyyyMMddhhmmss"); tmp['MSH']['MSH.10']['MSH.10.1'] = UUIDGenerator.getUUID();
Name: Patient ID
Type: JavaScript
Script:
Code:
tmp['QPD']['QPD.3']['QPD.3.1'] = getPatientID();
function getPatientID() { var patientId = '';
for ( var i = 0; i <= 9; i++ ) {
patientId += Math.floor( (Math.random() * 10) );
}
return patientId; };
Name: Query Tag
Type: Message Builder
Script:
Message Segment: tmp['QPD']['QPD.2']['QPD.2.1']
Mapping: tmp['MSH']['MSH.10']['MSH.10.1'].substring(10)

Name: TEST ONLY
Type: JavaScript
Script:
Code:
if ( 'ERR2' == msg['MSH']['MSH.9']['MSH.9.2'].toString().toUpperCase() ) {
if ( Math.floor((Math.random()*10)+1) > 5 ) tmp['MSH']['MSH.9']['MSH.9.1'] = 'QQQ';
if ( Math.floor((Math.random()*10)+1) > 5 )
tmp['MSH']['MSH.9']['MSH.9.2'] = 'E99'; if ( Math.floor((Math.random()*10)+1) > 5 )
tmp['MSH']['MSH.12']['MSH.12.1'] = '9.9';
}

From Destination Mappings I drag and drop Encoded Data into the box. I save changes and deploy channel. I try to send this sample HL7 as a message:

MSH|^~\&|ADM|Sending Organization|ALL|Receiving Organization|||QBP^E22^QBP_E22||D|2.7|||AL|AL QPD|E22^Authorization
Request^CIHI0003||^^^ISO^PHN|Everywoman^Mary^Patri ck^^^^L^|19680120|MSP^|EXT RCP|I

I get the following error even though I followed the book exactly:

Code:
Transformer error

29: }
30: function doScript() {

Does anyone have any idea why this is happening or how to troubleshoot?

Default Figured out my problem!!

Just in case anyone else is having the same problem I realized that the book's sample HL7 message had spaces where it shouldn't therefore the transformer couldn't parse the message properly. Below is the correct HL7 message without the spaces. (Do not include quotes)

"MSH|^~\&|ADM|Sending Organization|ALL|Receiving Organization|||QBP^E22^QBP_E22||D|2.7|||AL|ALQPD|E 22^AuthorizationRequest^CIHI0003||^^^ISO^PHN|Every woman^Mary^Patrick^^^^L^|19680120|MSP^|EXT RCP|I"
