 Hello @Ashish Das,

Can you please share the screenshot what error you are getting? and once verify your script.

@Ashish Das setPreference is usually available with spUtil (https://developer.servicenow.com/dev.do#!/reference/api/vancouver/client/spUtilAPI#SPU-setPreference...) or GlideModel (https://developer.servicenow.com/dev.do#!/reference/api/vancouver/client/c_GlideModalV3API#r_GMODV3-...

Since you are not using none of these objects to call this method on the client side, I doubt if it will work.
