How to Print Stack Trace via Script

[The SN Nerd]

Does anyone know if it is possible to print a stack trace out from a try/catch? I want to find out the line of code to store in an error record for my application.

Example code:

try {
         var gr = new GlideRecord('incident');
         var test = gr.madeUpFunction();
         test.adssad();
} catch (e) {
         var stackTrace = e.????;
         gs.print('Stack trace: ' + stackTrace);
}

Expected output:

Evaluator: org.mozilla.javascript.EcmaError: "est" is not defined.

  Caused by error in script at line 4

  1:

  2: var gr = new GlideRecord('incident');

  3: var test = gr.madeUpFunction();

==> 4: est.adssad();

Evaluator: org.mozilla.javascript.EcmaError: "est" is not defined.

  Caused by error in script at line -1

It is not enough information.

I'm deploying an application at my company that is still in early stages and I really need to know exactly where in my code the errors are being thrown.

Hi @The SN Nerd 
There is another callable function in GlideLog:

gs.log(new GlideLog.getStackTrace(new Packages.java.lang.Throwable()));

This does not throw me any error. Do I need to enable any property for this to throw error?

Example code is meant to be this sorry

1. try {  
2.         var gr = new GlideRecord('incident');  
3.         madeUpVariable.madeUpFunction();  
4. } catch (e) {  
5.         var stackTrace = e.????;  
6.         gs.print('Stack trace: ' + stackTrace);  
7. }

Hi Paul, the following is what I believe you have available for an exception:

try { 

         var gr = new GlideRecord('incident'); 

         madeUpVariable.madeUpFunction(); 

} catch (e) { 

         gs.print('LineNumber :' + e.lineNumber);

         gs.print('SourceName :' + e.sourceName);

         gs.print('Name: ' + e.name);

         gs.print('Message : ' + e.message);       

} 

outcome:

*** Script: LineNumber :3

*** Script: SourceName :<refname>

*** Script: Name: ReferenceError

*** Script: Message : "madeUpVariable" is not defined.

Thanks,
