Happens when you do gooey.dynamic_list(...) before gooey.vertical_scrollbar(...) in on_input(..) or init(...) (as if you use update_list(gooey.dynamic_list(...)) on init(...))
dynamic_list will call update_list before gooey.vertical_scrollbar(...) so action will always have been nil.
Workaround is to pass the expected variables in init(...) before update_list like gooey.vertical_scrollbar("scrollbar/handle", "scrollbar/bar", nil, {x=0, y=0})
