Value in table always prints nil?

--[[{"Destructable":true,"Health":20,"State":"Crate1","Holdable":true}]] --(table)
function grabData(object)
    local dataTable
    if object:WaitForChild("Data",0.001) then
        dataTable = game:GetService("HttpService"):JSONDecode(object.Data.Value)
    end
    print(dataTable.Holdable) -- always prints nil?
    if dataTable == nil then return nil else return dataTable end
end

It should print true, but always prints nil, even when there is a value for it?
