Using require(), I keep getting an error?

How exactly do I use require?

The script in ServerScriptService has this code in it:

local module = require(2293721179)
module.Parent = game.ReplicatedStorage


while true do
        wait(.6)
    module.heck()
end

and my module has this in it:

local module = {}


module.heck = function()
    for i,v in pairs(game:GetDescendants()) do
        print(v)
    end
end

return module

I thought this would work but it keeps giving the error:

unable to find module asset id even though the asset id is correct?? How do I fix this...

Thanks in advance for any help.
