"attempt to index local 'Player' (a nil value)" How to fix this error?

game.Workspace.CaseD.Touched:connect(function(User)
wait(.5)
if User.Parent:FindFirstChild("Humanoid") then
local Player = game.Players:GetPlayerFromCharacter(User.Parent)
if Player.TeamColor == "Bright bluish green" and KF.Value == false then
KF.Value = true
script.Parent.ServerEffects.Flag:Clone().Parent = User.Parent.Head
end
end
end)

check isnt Player nil. TeamColor is a brickcolor, not string.

game.Workspace.CaseD.Touched:connect(function(User)
wait(.5)
if User.Parent:FindFirstChild("Humanoid") then
local Player = game.Players:GetPlayerFromCharacter(User.Parent)
if Player ~= nil then
if Player.TeamColor == BrickColor.new("Bright bluish green") and KF.Value == false then
KF.Value = true
script.Parent.ServerEffects.Flag:Clone().Parent = User.Parent.Head
end
end
end
end)

EDIT: Try now
