How to combine remote events and ontouched event?

This is the sender (server script)

-- Server script
Detector = script.Parent.DetectorFront
Reset = true
local Players = game:GetService("Players")
cameraA = game.ReplicatedStorage.cameraA

Detector.Touched:connect(function(hit)
	local plr = hit.Parent
	if plr:FindFirstChild("Humanoid") then
		if Reset == true then
			local Player = hit.Parent
			cameraA:FireClient(Player)
			Reset = false
			wait(20)
			Reset = true
		end
	end
end)

This is the script that should answer the server script (local script)

--local script
local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:wait()
local Camera = workspace.CurrentCamera
local TA = workspace:WaitForChild("Bosses")
local TB = TA:WaitForChild("Red")
local TC = TB:WaitForChild("Red")
local target = TC:WaitForChild("Humanoid")
local player = Players.LocalPlayer
local cameraA = ReplicatedStorage:WaitForChild("cameraA")

cameraA.OnClientEvent:connect(function()
	print("accepted")
    Camera.CameraSubject = target
wait(5)
	Camera.CameraSubject = game.Players.LocalPlayer.Character.Humanoid
end)

I keep getting the error: "Player argument has to be a player object roblox" The script should fire cameraA remote event when the player touches the detector and then the localscript should make the player watch a certain brick
