I am geting this when I attempt to use I understand that “argument of type ‘NoneType’ is not iterable” may be due to none being being passed as a variable?

how can I find out exactly where the “argument of type ‘NoneType’ is not iterable” in this error , what is it exactly referring to ?

how can I track down this error , what is it talking about ? how can I get more information ?
