UPDATE : the problem just comes from the name of the module which was “Remotes” which I modified by “RemoteModule” 
I am currently creating a secure remote module with a “Hash” name, (HashLib) But I don’t understand something because on the client side it creates the event for me as required but as soon as I call the module on the client side server I get the following error:
Attempted to call require with invalid argument(s).
To tell you everything, I searched the forums and couldn’t find anything 
There is the module :
local replicatedStorage = game:GetService("ReplicatedStorage")
local RunService = game:GetService("RunService")
local Libraries = replicatedStorage:WaitForChild("Librairies")
local hasLib = require(Libraries.HashLib)
local Remotes = {}
function Remotes.Event(RemoteName)
local EncryptedName = hasLib.bin_to_base64(hasLib.hex_to_bin(hasLib.sha1(RemoteName)))
if not script:FindFirstChild(EncryptedName) then
local RemoteEvent = Instance.new("RemoteEvent")
RemoteEvent.Name = EncryptedName
RemoteEvent.Parent = script
return RemoteEvent
end
local RemoteInstance = script:WaitForChild(EncryptedName, 4)
if RemoteInstance == nil then error("Couldn't get RemoteEvent " .. RemoteName, 2) end
return RemoteInstance
end
return Remotes
here is an example of how I subsequently call the client and server module
-- Client
local remoteModule = require(replicatedStorage.Remotes)
local name = "John"
remoteModule.Event("Name"):FireServer(name)
-- Server
local remoteModule = require(replicatedStorage.Remotes)
remoteModule.Event("Name").OnServerEvent(player, name)
print(`{player.Name} --> {name}`)
end)
the error occurs when I call the server side module
If anyone could help me I would be indebted!
