Bad argument #3 to 'Position' (expected Vector3, got object) how do I fix it?

I want to change the position of the part based on the CFrame of the mouse, but I get this error: Bad argument #3 to 'Position' (expected Vector3, got object) I am using a RemoteEvent to transfer the CFrame value from the client to the server.

Here is the LocalScript:

local replicatedstorage = game:GetService("ReplicatedStorage")
local Player = game.Players.LocalPlayer -- Also, I noticed you weren't using 'local' to define your variables. Use that, as it sets the variable apart from a global variable.
local Mouse = Player:GetMouse()
local MouseCFrame = Mouse.Hit
local MousePosition = MouseCFrame.p

local event = replicatedstorage:WaitForChild("TestEvent")

function printpos()
    MouseCFrame = Mouse.Hit
    MousePosition = MouseCFrame.p
    event:FireServer(MousePosition)
    print (MousePosition)
end

Mouse.Button1Down:Connect(printpos)

Here is the Script for the server:

local replicatedstorage = game.ReplicatedStorage
local event = Instance.new("RemoteEvent")
event.Name = "TestEvent"
event.Parent = replicatedstorage

local part = game.Workspace.test

function movePart(coords)
    part.Position = coords
    print(coords)
end

event.OnServerEvent:Connect(movePart)

First of all this

function printpos()
    MouseCFrame = Mouse.Hit
    MousePosition = MouseCFrame.p
    event:FireServer(MousePosition)
    print (MousePosition)
end

was unnecessary all you needed to do was this

function printpos()
    event:FireServer(Mouse.Hit.p)
    print(Mouse.Hit.p)
end

Try that other than that i dont know why its tripping

it doesn't work because in the script (not the localscript) the coords variable is actually the player who fired the remote event so do this

local replicatedstorage = game.ReplicatedStorage
local event = Instance.new("RemoteEvent")
event.Name = "TestEvent"
event.Parent = replicatedstorage

local part = game.Workspace.test

function movePart(plr,coords)
    print(coords)
    part.Position = coords

end

event.OnServerEvent:Connect(movePart)

so now the coords variable is actually the coordinates Questofmagicfarts 55 — 5y
