Question
Hi, im trying to add sound options to my game, but im gettin this error.  and this are bus  sounds nodes also set for the bus "sfx" or "master" so what could it be ?
It looks like get buss index is returning -1 which is out of bounds for any array. Check to make sure your “sfx” bus does not have white space at the end "sfx "
thanks for the anwser, but i solve the problem 
aperenty there is a setting in project settings–> Application → Audio → Default Bus Layout, after you set your bus, save it and chose as a Default Bus Layout. and its work.
