GetPlayerFromCharacter is not a valid member of Model?

I have recently discovered a bug in one of my infection games that cause all players to have the infection animation play when one of the players touches a hazard. I am currently reworking the code, this time attempting it with the GetPlayerFromCharacter() function. However, now that I implemented this, I get an error in the console that says GetPlayerFromCharacter is not a valid member of Model "Workspace.Crimsonknightzone" How do I fix this?

Here is the code, it's on a local script

local debounce = false
local puddle = game.Workspace.GooClusterMPE.Puddle
local starterPlayer = game:GetService("StarterPlayer")
local plr = game.Players.LocalPlayer
local char = plr.Character
puddle.Touched:Connect(function(touch)
    if game.Players.LocalPlayer.Team == game.Teams.Humans then
        debounce = true
        local playerWhoTouched = touch.Parent
        local Player = playerWhoTouched:GetPlayerFromCharacter()
        local Character = Player.Character
        local animation = game.Workspace.Anims.Animation
        local animtrack = Character.Humanoid:LoadAnimation(animation)
        local debounce = true
        local sound = game.Workspace.Sound
        Character.Humanoid.WalkSpeed = 0
        game.Players.LocalPlayer.Team = game.Teams.Infected
        animtrack:Play()
        local repStore = game:GetService("ReplicatedStorage")
        local Human = touch.Parent
        local sound = game.Workspace.Sound
        sound:Play()
        repStore.Transfurs.MPEGoo:FireServer()
        wait(1.1)
        sound:Play()
        wait(2.9)
        sound:Play()
        wait(1)
        sound:Play()
        Character.Humanoid.WalkSpeed = 16
    end
end)
game.Players.LocalPlayer.Character.Humanoid.Died:Connect(function()
    plr.Team = game.Teams.Humans
end)
