Instead of value is "NULL" it was creating the empty record

[balajibs]

Please find the script below. I am trying to insert the "value" field as a "NULL" string, but it is creating an empty record. Does anyone know why the string is being converted into an empty record?

Script:
var gr = new GlideRecord("sn_ti_observable");
gr.initialize();
gr.value = "NULL";
gr.insert();

Hi,

What is the data type of the field "value"?

Check if the field's backend name is correct or not

Hi Amaradiswamy,

Thanks for your response.

Datatype is "String." I have checked the backend name; also, it's correct.

Whenever I tried with gr.value="xyz.com," it was properly updating into the field. But gr.value="NULL," then an empty record is created.

Hello @balajibs , 

Using the string "NULL" as a value is not expected  in ServiceNow. When assignig this value, the fieald is automatically cleared. 

Please consider using a different  word or assign a value like "N U L L" instead.

Best regards,
