Hi @Devansh00 ,

In your ATF script , somewhere you have used replace() function which is not supported by Servicenow.

The error "Cannot read properties of null (reading 'replace')" occurs when your ServiceNow client-side code executes a .replace() string function on a variable or field that contains no data or evaluates to null

For example:

var value = null;

var result = value.replace("old", "new");

Change the replace() by some supported function .

You ca share the code snippet as well .
