Argument converts to something else when going through a RemoteFunction?

LocalScript:

UIS.InputBegan:connect(function(input)
    if input.KeyCode == Enum.KeyCode.E then
        workspace.RFpurchase:InvokeServer(lplayer, nearShop)
    end
end)

repeat wait(.5) until lplayer.PlayerGui.Hud.Overlay
local overlay = lplayer.PlayerGui.Hud.Overlay
while wait(.1) and lplayer.Character.Humanoid.Health > 0 do
    print(nearShop) -- ''HealthCrateShop'' or ''false'' depending on whether the If statement below passed
    for i, v in pairs(workspace:GetChildren()) do
        if v:FindFirstChild'Shop' then
            local distance = (v.ShopPart.Position - lplayer.Character.Torso.Position).magnitude
            if distance < 10 then
                nearShop = v
                overlay.Visible = true
                overlay.Text = v.OverlayText.Value
            else
                overlay.Visible = false
                nearShop = false
            end
        end
    end
end

ServerScript: (inside the shop part)

bought = false
price = 150
function workspace.RFpurchase.OnServerInvoke(lplayer, nearShop)
    print(nearShop) -- ''Player1'' regardless of what was printed in the localscript
    if lplayer and lplayer.Character:FindFirstChild('Humanoid') and nearShop == script.Parent then
        if lplayer.Character.Humanoid.coins.Value >= price then
            lplayer.Character.Humanoid.coins.Value = lplayer.Character.Humanoid.coins.Value - price
            if not bought then
                bought = true
                for i=1, 7 do
                        local pickup = game.ReplicatedStorage.pickup:Clone()
                    pickup.BillboardGui.ImageLabel.ImageColor3 = Color3.new(0, 0, 1) -- hp
                    pickup.Parent = workspace
                    pickup.Position = script.Parent.lite.Position
                    pickup.Velocity = Vector3.new(math.random(-25, 25), 25, math.random(-25, 25))
                    pickup:BreakJoints()
                end
                script.Parent.lite:Destroy()
            end
        end
    end
end

This is probably something to do with me getting remotefunction arguments mixed up, but I don't know what I did wrong, so i'd like some help.
