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.
