Response transformer issue

[rutledj]

I'm trying to convert a MSA|AE response to one accepted (MSA|AA)

A bad one looks like this:

MSH|^~\&|MIRTH||EPIC|METNEPASS|20250204160827||ACK|20250204160827|P|2.3
MSA|AE|143874451|An Error Occured Processing Message.

I tried the below code in a response transformer, but it doesn't seem to ever enter the if statement:

for each(org in msg..MSH['MSH.6'])
{
	if(org != 'DNANC' && org != 'ENANC' & org != 'CKCNC')
	{
		// Retrieve the original response message
		var response = responseMap.get('responseMessage');
		//logger.info('Response: ' + response.toString());
		
		// Check if the response is a NACK
		if (response && response.startsWith('MSA|AE')) 
		{  // Adjust condition based on actual NACK structure
		    logger.info("Received NACK, converting to ACK...");
		    
		    // Construct an ACK message based on the original NACK
		    var ackMessage = response.replace('MSA|AE', 'MSA|AA');  // Change 'AR' (Application Reject) to 'AA' (Application Accept)
		    
		    // Set the modified message as the final response
		    responseMap.put('responseMessage', ackMessage);
		    break;
		}
	}
}

If MSH-6 isn't one of those values that I will get an ack back with an MSA|AE| in it.

Would appreciate any advice.
