***TypeError: 'NoneType' object is not iterable***

now am doing this line commands but also nothing changed ! any help please ?

desk.min.css is build from other files so you should change in that particular file.
check this file you will get and idea.

if you change in desk.min.css and then try to bench build it will override your changes.

bench --site site_name clear-cache will solve your problem
