Default Replacing tag names with their semantinc description ERROR

I'm getting this error
Transformer error

with the following code in the transformer
String.prototype.escape = function() {return (this+'').replace(/[\s\/<>',]/g,'')};

for each (seg in msg.children()) {
	if (seg.name()) {
		seg.setName(Component.getSegmentDescription(seg.name().toString()).escape() || seg.name());
	for each (field in seg.children()) {
		if (field.name()) {
			field.setName(Component.getSegmentorCompositeFieldDescription(field.name().toString(),false).escape() || field.name());

		for each (component in field.children()) {
			if (component.name()) {
				component.setName(Component.getCompositeFieldDescriptionWithSegment(component.name().toString(),false).escape() || 'Value');
return msg;
The intention from this code is to change the name of the xml namespaces with their full name , thing is in some messages i'm getting this exception (the majority of the messages pass the code and are correctly changed)
Please i'm asking for help

That's a pretty neat bit of code.

The message I tried was failing with the same error message because of a description containing parentheses, which aren't in your escape function. It seems to fail hard enough that you can't even mitigate it by putting a try/catch around the call to setName().

You can remove the return msg; from the end of your code. Returning in a transformer will cause any remaining transformer steps to skip. The return value is not used.

As an alternative you could set a description attribute rather than renaming the element. Then you won't need to worry about bad characters in the name. Something like this:

const Component = com.mirth.connect.model.hl7v2.Component;

var desc;
for each (var seg in msg.children()) {
	if (desc = Component.getSegmentDescription(seg.name().toString())) { seg.@desc = desc; }

	for each (var field in seg.children()) {
		if (desc = Component.getSegmentorCompositeFieldDescription(field.name().toString(),false)) { field.@desc = desc }

		if (field.hasSimpleContent()) continue;

		for each (var component in field.children()) {
			desc = Component.getCompositeFieldDescriptionWithSegment(component.name().toString(), false);
			if (desc) { component.@desc = desc }

Thank you for your answer , and based on your answer adding the parantheses to my script would avoid the break and fix the errors ,
String.prototype.escape = function() {return (this+'').replace(/[\s\/<>',]/g,'').replace('(','').replace(')','')};
that fix it though?
