The error message indicates that there is an empty JSON string on line 1654 of the code. This error is preventing the transformer from being evaluated properly. It seems that the transformer is part of a channel called HTTP_HWSAFE_DOCUMENT_TO_HL7_ORU_AHC, and the error is occurring in the source connector. The error message also includes a stack trace that shows the sequence of events leading up to the error.

Transformer Code we Using

var messageType = "";
var messageEvent = "";
var objJson = JSON.parse(messageObject.getRawData());

channelMap.put('messageDateTime', DateUtil.getCurrentDate("yyyyMMddHHmmss"));
channelMap.put('accessionId', msg['accessionId']);
channelMap.put('patientName', msg['patientName']);
channelMap.put('patientId', msg['patientId']);
channelMap.put('patientAccNum', msg['patientAccountNumber']);

if (msg['OrganizationID'] !== "") {
    if (msg['OrganizationID'] === "Athens Medical Center") {
        messageType = "ORU";
        messageEvent = "R01";
        channelMap.put('messageEventType', messageType + "^" + messageEvent);
    }
}

channelMap.put('date', DateUtil.getCurrentDate('yyyyMMdd'));
channelMap.put('fileName', msg['patientId'] + "_" + msg['patientName'] + ".json");

Filter logic I'm Applying to resolve this Error

if(connectorMessage.getRawData().toString().length() > 0 ) {
return true;
} else {
return false;
}

But Still getting the Same error

can anyone help me to resolve that error or explain me how to do that.

determineVariableType

/**
 * Determines the type of a given variable. 
 * If the variable is a Java instance, it returns the Java class name.
 * If the variable is a JS object, it returns the JS constructor name (if available) 
 * or extracts the type from the default toString representation (as a fallback).
 * Otherwise, it returns the JS primitive type.
 * 
 * @param {any} variable The variable whose type needs to be determined.
 * @return {string} The type of the variable.

Pull data from Filename

I need to take a date out of the filename to add to the HL7 output.
Filename example: MRMC_Epic_Demo_2024-2-29.txt
Not sure how to do this in the Transformer to use to strip away the "MRMC_Epic_Demo_" and ".txt"

Convert multiple input date formats to a single out format

I get Date of Birth in two formats (YYYYMMDD and YYYYMMDDHHMMSS) and then need to output in a single format of MM-DD-YYYY.
I can convert one or the other to MM-DD-YYYY but don't know how to write an if then else statement in Java to convert whichever one is sent over.
I am no expert in Java scripting so any help would be appreciated. What I have used in the transformer is
DateUtil.convertDate("yyyy-MM-dd", "MM-dd-yyyy", msg['PID']['PID.7']['PID.7.1'].toString());
or
DateUtil.convertDate('yyyyMMdd','MM-dd-yyyy',DOBouput)
