Getting Error in Widget

[Michael48]

I have a code am working on where i want users with a specific role should be able to view the records in the query below. it seems to be working but its throwing the error in the screen shot.

Here is the code

var gr = new GlideRecord('x_verw2_ac_factory_af_opportunity');

gr.addQuery('u_state','!=','Draft');//only draft records should be visible

var grOr= gr.addQuery('u_requested_by' , gs.getUserID());

grOr.addOrCondition('requester_delegate',gs.getUserID());

grOr.addOrCondition(gs.getUser.hasRole("x_verw2_ac_factory.super_user")); //(my line of script that's throwing the error)

gr.query();

while(gr.next()){

del.push(gr.number.toString());

}

If the user has this role x_verw2_ac_factory.super_user they should all records that is not in draft state but if they dont have that role they should the  records where there they are the requester or delegate of

i observed now that it just keeps searching when you have the role, it doesnt load the data in the drop down.
