Script works, but outputs "Attempt to index nil with `FindFirstChild`when looking at sky?

The script (localscript) works as intended, but whenever I playtest, it outputs "Attempt to index nil with FindFirstChild, (only when looking at the sky.) This makes it next to impossible to read anything in the output, since it's being occupied by a gazillion of these errors. Here's the script, hope someone can help:

`local player = game.Players.LocalPlayer local mouse = player:GetMouse()

mouse.Move:Connect (function() local target = mouse.Target

if target:FindFirstChild ("dex") then
	target.dex.Enabled = true
	if target.Transparency == 1 then
		target.dex.Enabled = false
	end
elseif target:FindFirstChild ("Berry") then
	target.Berry.dex.Enabled = false
end		

end)`

I'm a rookie at coding, so don't judge if the code's terrible ????

the problem is that you not checking if target exists, when u look at the sky, There's nothing (unless theres a part in the sky) so target is nil, to fix it, add another if statement to check if target exists and if it has a parent

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

mouse.Move:Connect (function()
	if mouse.Target then -- check if there's a target else it'll error
		local target = mouse.Target
	end
end

if target and target.Parent then
	if target:FindFirstChild ("dex") then
		target.dex.Enabled = true
		if target.Transparency == 1 then
			target.dex.Enabled = false
		end
		elseif target:FindFirstChild ("Berry") then
			target.Berry.dex.Enabled = false
		end
	end
end
