g_form.setReadOnly() method not working when I run it through Client Script, but it works when I run the same on the JavaScript Executor(Ctrl + Alt + Shift + J), is there a way to debug and know what is stopping my Client Script code to not work on setting the field read only. 

The Client Script is:

Hi Rahul,

                 Put the  g_form.setReadOnly('item', true); after completing the first brace. It will work both mandatory and readonly function.

What UI type is your client script set to?

I'm not sure if ServiceNow supports forEach in scripts. Can you try converting it to a for loop? 

for( var i = 0; i < fieldsArray.length; i++) {
    g_form.setReadOnly(fieldsArray[i], true);
}

Check if your client script is in the same scope of the field.
