How to fix com.glide.ui.ServletErrorListener source error ?

[kun1]

Hi All,

While check the error in the system logs, i am getting "Root cause of JavaScriptException: java.lang.NullPointerException
: java.lang.NullPointerException:" error whose source is com.glide.ui.ServletErrorListener.

Code:-

JavaScript evaluation error on:
var data_string = source.u_whendisabled;
//convert date in .OZ format to sting
var when_disabled = data_string.substring(0,4)+'-'+data_string.substring(4,6)+'-'+data_string.substring(6,8)+' '+data_string.substring(8,10)+':'+data_string.substring(10,12)+':'+data_string.substring(12,14);

//set date based on US/Eastern time zone
var gDate = GlideDateTime();
gDate.setValue(when_disabled);

///substract offset based on time zone between UTC and US/Eastern
var offset = gDate.getTZOffset();
gDate.add(offset);

answer = gDate;
Root cause of JavaScriptException: java.lang.NullPointerException
: java.lang.NullPointerException:

Can some help me where can i find this this , whats the issue in this code and how can we resolve this?

Thanks!

Can you check value of "when_disabled" variable before this gDate.setValue(when_disabled).

I suspect there is some issue in line 2 code

var when_disabled = data_string.substring(0,4)+'-'+data_string.substring(4,6)+'-'+data_string.substring(6,8)+' '+data_string.substring(8,10)+':'+data_string.substring(10,12)+':'+data_string.substring(12,14);

This i found in the sys_transform_entry as a source script. the field u_whendisabled i mapped to user table AD disabled field. I think beacuse AD disabled is empty in the source table because of this error will come. am i right?

Its might be, the value is coming empty. You can always check by applying gs.log(source.u_whendisabled) or gs.info(source.u_whendisabled) in your script.

and 

instead of directly passing value you can use check the value

var data_string = source.u_whendisabled;
//convert date in .OZ format to sting
if(data_string!=''){
var when_disabled = data_string.substring(0,4)+'-'+data_string.substring(4,6)+'-'+data_string.substring(6,8)+' '+data_string.substring(8,10)+':'+data_string.substring(10,12)+':'+data_string.substring(12,14);

//set date based on US/Eastern time zone
var gDate = GlideDateTime();
gDate.setValue(when_disabled);

///substract offset based on time zone between UTC and US/Eastern
var offset = gDate.getTZOffset();
gDate.add(offset);

answer = gDate;
}

var data_string = source.u_whendisabled;
//convert date in .OZ format to sting
if(source.u_whendisabled!="")
{
var when_disabled = data_string.substring(0,4)+'-'+data_string.substring(4,6)+'-'+data_string.substring(6,8)+' '+data_string.substring(8,10)+':'+data_string.substring(10,12)+':'+data_string.substring(12,14);

//set date based on US/Eastern time zone
var gDate = GlideDateTime();
gDate.setValue(when_disabled);

///substract offset based on time zone between UTC and US/Eastern
var offset = gDate.getTZOffset();
gDate.add(offset);

answer = gDate;
}

i have added "if(source.u_whendisabled!="")" in my code. is code looks ok now?
