confirm not working. It seems $json failed to parse %data.

Here is how i tested it.
/followers.update -s #mark_paintball

Tried to debug using echo between this line
Code:
var %i = 0, %n = $json(%data,follows).count, %new.count
echo -a n value is %n
while (%i < %n) {

It did hmake hashtable, after that it seems %n is $null so while loop never being executed.
