Why is it erroring checking for gamepass in localscript?

Error: "Cannot find player.userid" What would be the correct format for localscript? I've tried without userid

    repeat wait(.1) until game.Players.LocalPlayer.Character ~= nil
repeat wait(.1) until game.Players.LocalPlayer.Character.Humanoid ~= nil
player = game.Players.LocalPlayer
mouse = player:GetMouse()

local char = player.Character
local roll = Instance.new("Animation")
roll.AnimationId = "rbxassetid://3027027786"
local animloader = char.Humanoid:LoadAnimation(roll)
function KeyD(key)
	if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.userid, 6014768) then
	key = key:lower()
	local hotkey = script.Hotkey
	
	if key == hotkey.Value then
		local animloader = char.Humanoid:LoadAnimation(roll)
		animloader:Play()
	end
	end
end

mouse.KeyDown:connect(KeyD)


function Move(key)
if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.userid, 6014768) then
key = key:lower()
if key == "w" or key == "a" or key == "s" or key == "d" then
animloader:Stop()
	end
end
end

mouse.KeyDown:connect(Move)

roblox updated userId to UserId, change that

the keyDown part needs to change to this

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

mouse.KeyDown:Connect(function(key)
	local Key = key.lower("key in here")
	if key == ("same key in here") then
		function here
	end
end)

userid needs to be properly formatted to UserId or it will error. Replace both instances of it in your script the error will stop. The updated script should look like this:

repeat wait(.1) until game.Players.LocalPlayer.Character ~= nil
repeat wait(.1) until game.Players.LocalPlayer.Character.Humanoid ~= nil
player = game.Players.LocalPlayer
mouse = player:GetMouse()

local char = player.Character
local roll = Instance.new("Animation")
roll.AnimationId = "rbxassetid://3027027786"
local animloader = char.Humanoid:LoadAnimation(roll)
function KeyD(key)
	if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.UserId, 6014768) then
	key = key:lower()
	local hotkey = script.Hotkey
	
	if key == hotkey.Value then
		local animloader = char.Humanoid:LoadAnimation(roll)
		animloader:Play()
	end
	end
end

mouse.KeyDown:connect(KeyD)


function Move(key)
if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.UserId, 6014768) then
key = key:lower()
if key == "w" or key == "a" or key == "s" or key == "d" then
animloader:Stop()
	end
end
end

mouse.KeyDown:connect(Move)

On a side note, KeyDown is deprecated due to its inability to detect multiple key presses at a time. A post on the developer wiki can be found here explaining how to integrate new and better key input methods into your game.
