Can someone explain why this datastore location handler is not working?

CODE:

local DataStoreService = game:GetService("DataStoreService")
local locationStore = DataStoreService:GetDataStore("LocationStore")

game.Players.PlayerAdded:Connect(function(player)
    local character = game.Workspace:WaitForChild(player.Name)
    
    local data
    local success, err = pcall(function()
        data = locationStore:GetAsync(player.UserId.."-position")
    end)
    
    if success then
        if data and data ~= {x = 0, y = 3, z = 0} then
            character.HumanoidRootPart.Position = Vector3.new(data.x, data.y, data.z)
        else
            print("No data found!")
            locationStore:SetAsync(player.UserId.."-position", {
            x = 0,
            y = 3,
            z = 0
            })
        end
    else
        warn("There was an error while getting data!")
        warn("Error code:", err)
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
    local character = game.Workspace:WaitForChild(player.Name)
    local success, err = pcall(function()
        locationStore:SetAsync(player.UserId.."-position", {
            x = character.HumanoidRootPart.Position.X,
            y = character.HumanoidRootPart.Position.Y,
            z = character.HumanoidRootPart.Position.Z
        })
    end)
    
    if success then
        print("Data successfully saved!")
    else
        warn("There was an error while saving data!")
        warn(err)
    end
    
end)
