Transposer cannot access inventories (nil - No inventory)

[mpolder 0]

For some reason my code to access a tranposer inventory is not working. I am trying to connect it to my Refined Storage ME system but when trying to connect it to a chest on top of the transposer it simply doesn't work.

 

Here is my code:

local component = require("component")
local sides = require("sides")
local transposer = component.transposer
local ser = require("serialization")
 
local selection = "minecraft:dirt"
local amount = 10

print(transposer.getInventorySize(sides.south))

Since you say the chest is on top of the transposer, you should use sides.top, not sides.south.
