Why does this RemoteFunction always return an empty table?

I'm learning how to use FilteringEnabled, and despite my best efforts, I can't figure out why or how this doesn't work. There are two scripts, one on the server side and one on the client side in a local script.

--SERVER SIDE:
--(assume "remote" variable is a RemoteFunction)
function getItems(plr)
    return game.ServerStorage.Items:GetChildren()
end
remote.OnServerInvoke=getItems

--CLIENT SIDE:
--(assume "remote" variable is the same RemoteFunction)
local remoteItems=remote:InvokeServer()

Here is all of the info I've been able to get so far: -The server side script returns a table with 1 item in it. -The client side script receives a table with no items in it (NOT nil). -Therefore, there must be something happening between the data send and the data receive.

Any help would be MASSIVELY appreciated, as I really want to drive my head through the screen right now.
