Error while calling functions of another script

[xanall9766]

I made a custom module loading in MoonSharp to load modules and the globals. The module is being loaded

Error

An error occured while executing script: chunk_1:(1,0-47): 
Attempt to perform operations with resources owned by different scripts.

Script:

local module = Modules.LoadModule("module.lua")

module.Foo()

module.lua

module = {}

function module.Foo()
    Logger.Log("Bar!", "green")
end

return module

Full method LoadModule

public DynValue LoadModule(Script script, string name)
{
       string full = ScriptManager.Instance.ScriptsDirectory + "\\" + name;

        if (!File.Exists(full))
        {
            Logger.Log("Cannot find", ConsoleColor.Red);
            return DynValue.Nil;
        }

        FileInfo scriptFile = new FileInfo(full);

        if (scriptFile.Extension != ".lua")
        {
            Logger.Log("Wrong extension", ConsoleColor.Red);
            return DynValue.Nil;
        }

        Script module = new Script();
        ScriptManager.Instance.LoadGlobals(module);

        DynValue moduleReturn = module.DoString(File.ReadAllText(scriptFile.FullName));

        DynValue moduleTable = DynValue.NewTable(script);
            
        foreach (DynValue e in moduleReturn.Table.Keys)
        {
            moduleTable.Table.Set(e.ToPrintString(), moduleReturn.Table.Get(e));
        }

        return moduleTable;
}

At present you're creating a new Script for the each Lua file. Each Script is essentially its own VM, so you're getting this error because you're trying to interact with Lua values that exist in another VM.

You could call LoadFile on the existing Script. However, there's built-in support for what you're after via https://www.moonsharp.org/scriptloaders.html

You could call LoadFile on the existing Script.

I tried LoadFile right now and i got an exception:

System.Exception: Cannot load script 'module.lua'. By default, scripts should be .txt files placed under a
Assets/Resources/MoonSharp/Scripts directory.
If you want scripts to be put in another directory or another way, use a custom instance of UnityAssetsScriptLoader or 
implement your own IScriptLoader (possibly extending ScriptLoaderBase).

I'm not using the UnityAssetsScriptLoader

script.Options.ScriptLoader = new FileSystemScriptLoader();
((ScriptLoaderBase)script.Options.ScriptLoader).ModulePaths = new string[] { "?.lua" };

And loading

DynValue moduleResult = module.LoadFile(scriptFile.FullName);

However, there's built-in support for what you're after via

if there's a way to load globals in require...

Yes, this is how require works by default in Lua, MoonSharp included. You'll want to setup a ScriptLoader as per the link above.
