This is a warning. Your code still works. You can configure accordingly.
Thank you
But is there any way to fix it

Check for the error. May save you some headache debugging down the line. E.g.
var err=turn_control.connect("turn_changed",self,"turn_changed")
if err:
print("Error", err)
but if you don’t care then do something like this by adding an underscore
var _err=turn_control.connect("turn_changed",self,"turn_changed")
There is a 3rd way but only works one variable at a time:
#warning-ignore:UNUSED_VARIABLE
var err=turn_control.connect("turn_changed",self,"turn_changed")
