Script Analysis !!

[SandeepKSingh]

Is it possible to print a stack trace from a try/catch block in ServiceNow? I want to capture the line of code where the error occurred and store it in an error record for my application.

try {
var x= new GlideRecord('incident');
var test = x.testFunction();
test.qwerty();
} catch (e) {
var stackTrace = e.????; // Need help here
gs.print('Stack trace: ' + stackTrace);
}
Expected Output:
I want something like this:
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.testFunction(); ==> 4: est.adssad();

Hi @SandeepKSingh 

try {
var gr = new GlideRecord('incident');

// Intentionally calling an undefined function to trigger an error
testVariable.testFunction();

} catch (e) {
gs.error('Exception occurred:');
gs.error('Line Number: ' + (e.lineNumber || 'N/A'));
gs.error('Source Name: ' + (e.sourceName || 'N/A'));
gs.error('Error Name: ' + (e.name || 'N/A'));
gs.error('Error Message: ' + (e.message || 'N/A'));
}
the above will give you an Idea

outcome:

*** Script: LineNumber :3

*** Script: SourceName :<refname>

*** Script: Name: ReferenceError

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