3d building system fails to function as intended, is there a reason why?

Here is my LOCAL script:

01local Players = game:GetService("Players")
02local Camera = workspace.CurrentCamera
03local UIS = game:GetService("UserInputService")
04local rs = game:GetService("RunService").RenderStepped
05local ReplicatedStorage = game:GetService("ReplicatedStorage")
06local Ghost = ReplicatedStorage.ItemIndicator
07local buildmode = true
08local Item = "Plastic Test Brick"
09Ghost.Parent = workspace

11local mousePos
12local mouseTarget
13local gridPos
14local canPlace

16function GetMousePoint(X, Y)
17    print("a")
18    local RayMag1 = Camera:ScreenPointToRay(X, Y) --Hence the var name, the magnitude of this is 1.
19    local NewRay = Ray.new(RayMag1.Origin, RayMag1.Direction * 1000)
20    local Target, Position = workspace:FindPartOnRayWithWhitelist(NewRay, workspace.Parts:GetChildren())
21    return Position
22end
23 
24function snap(num) return math.floor(num/4+0.5)*4 end

29        print("c")
30        Ghost.Parent = workspace
31        mousePos = GetMousePoint(UIS:GetMouseLocation().X, UIS:GetMouseLocation().Y)
32        gridPos = Vector3.new(snap(mousePos.X), snap(mousePos.Y), snap(mousePos.Z))
33        Ghost.CFrame = CFrame.new(gridPos)
34        print("d")
35 
36        local region = Region3.new(Ghost.Position+Ghost.Size/2.1, Ghost.Position-Ghost.Size/2.1)
37        print("l")
38        local parts = workspace:FindPartsInRegion3(region, Ghost)
39 
40        if #parts > 0 then
41            print("e")
42            Ghost.Color = Color3.fromRGB(255, 89, 89)
43            canPlace = false
44        else
45            print("f")
46            Ghost.Color = Color3.fromRGB(123, 255, 93)

Here is my SERVER script, but I don't think the problem is it:

01local rs = game:GetService("ReplicatedStorage")
02local ss = game:GetService("ServerStorage")
03 
04rs.PlacePart.OnServerEvent:Connect(function(player, position, partType)
05    local part = ss:WaitForChild(partType, 5):Clone()
06    if part then
07        part.Position = position
08        part.Parent = workspace
09    else
10        error("Part Failed to Load")
11    end
12end)

P.S. There are no errors in the output.

The problem I have is that when using the grid movement, these three things happen:

Parts fail to go to the right area
Ghost part fails to turn red when region3 detects a problem
Bricks do not get placed

Here's a gif if it makes it easier: https://gyazo.com/cdb07c9616926c4bdd99ce4a5eca1d51

I've tried countless times to make this work, but I can't seem to get it right, thank you if you can solve it!
