Problem with my laser gun code? [UN-ANSWERED]

I get the error "TeamColor is not a valid member of model" whenever I hit someone. I'm not sure why it does this, because it checks for player and player isn't their character, unless i'm wrong.

Also, lines 23-27 is where the problem is.

local tool = script.Parent

local reloadTime = 1;
local reloading = false;

tool.Equipped:connect(function(mouse)
    local user = tool.Parent
    local plr = game.Players.LocalPlayer
    mouse.TargetFilter = user

    mouse.Button1Down:connect(function()
        if reloading then
            return
        end

        if user:FindFirstChild("Humanoid") and user.Humanoid.Health > 0 then
            reloading = true

            local ray = Ray.new(tool.Handle.CFrame.p, (mouse.Hit.p - tool.Handle.CFrame.p).unit * 300)
            local hit, position = game.Workspace:FindPartOnRay(ray, user)

            local humanoid = hit and hit.Parent and hit.Parent:FindFirstChild("Humanoid")
            local player = game.Players:GetPlayerFromCharacter(hit.Parent)

            if humanoid and player.TeamColor ~= user.TeamColor then
                humanoid:TakeDamage(15)
            end

            local distance = (position - tool.Handle.CFrame.p).magnitude
            local rayPart = Instance.new("Part", workspace)
            rayPart.Name = "RayPart"
            rayPart.BrickColor = plr.TeamColor
            rayPart.Transparency = 0.5
            rayPart.Anchored = true
            rayPart.CanCollide = false
            rayPart.TopSurface = Enum.SurfaceType.Smooth
            rayPart.BottomSurface = Enum.SurfaceType.Smooth
            rayPart.formFactor = Enum.FormFactor.Custom
            rayPart.Size = Vector3.new(0.2, 0.2, distance)
            rayPart.CFrame = CFrame.new(position, tool.Handle.CFrame.p) * CFrame.new(0, 0, -distance / 2)

            game.Debris:AddItem(rayPart, 0.1)

            local start_t = tick()

            while game:GetService("RunService").RenderStepped:wait() do
                if tick() - start_t() > reloadTime then
                    break 
                end
            end

            reloading = false
        end
    end)
end)
