"Attempt to load a function from a different lua VM"

[IAmReallyNewb]

Hello, so I’m creating this block coding system for a game. However, whenever I try and run my test block data script, this error pops up:

 Attempt to load a function from a different Lua VM  -  Server - Script:14
  19:37:24.944  Stack Begin  -  Studio
  19:37:24.945  Script 'Workspace.Script', Line 14 - function runBlockData  -  Studio - Script:14
  19:37:24.945  Script 'Workspace.Script', Line 22  -  Studio - Script:22

This is my test executor module as well as the “ComposeVector3” module that I’m loading:

--!native
local runService: RunService = game:GetService("RunService")
local isServer: boolean = runService:IsServer()

if not isServer then return 0 end

local lookupTable: {[string]: {[string]: any}} = require(game.ReplicatedStorage.ExecutorData.BlockData)
local blockFuncs: {[string]: () -> any} = game.ServerStorage.Messages.GetBlockFuncs:Invoke()
local scriptData: {[string]: any} = {Variables = {}}

local function runBlockData(data: {[number]: {[string]: string | number}})
	for id: number, blockData: {[string]: string | number} in ipairs(data) do
		local status: {[string]: boolean | any} = blockFuncs[blockData.Id](data.Parameters, scriptData)
		assert(data.Success, data.Value)
		
		if #blockData.ConnectedBlocks > 0 then runBlockData(blockData.ConnectedBlocks) end
	end
end

local start: number = os.clock()
runBlockData({{Id = "ComposeVector3", Parameters = {X = 10, Y = 20, Z = 30, Vector3Variable = "AwesomeSauce"}, ConnectedBlocks = {{Id = "Print", Parameters = {Variable=Vector3.new(10,20,30)}, ConnectedBlocks = {}}}}})
scriptData["Benchmark"] = os.clock()-start
return scriptData

ComposeVector3 module:

--!native
return function(data: {[string]: any}, scriptData: {[string]: any})
	local result: Vector3 = Vector3.new(data.X, data.Y, data.Z)
	scriptData.Variables[data.Vector3Variable] = {Value = result, Type = typeof(result)} 
end

I think the issue has to do with scriptData.Variables, and if so, how would I go about changing the variable data without causing this error to appear?

You cannot use functions that you got returned from or passed to a bindable or remote event.

An overcomplicated look into Bindable immutability

Warning: this resource delves into some pretty complex topics with Roblox. Bindables can act strangely when you pass functions, or tables with metatables or functions. This guide aims to explain why this happens and what’s actually happening. Luau VMs Roblox isolates every script context into it’s own global state, in this resource I’m going to refer to them as ‘VM stacks’. Edit Note Each of these stacks have an isolated memory, which means Luau itself cant fetch values from one stack and g…

That clarifies it up, let me try it out. By the way, is there any way to give more context in script errors? I really don’t want to counter one of these again.
