"attempt to index nil with 'CFrame'" but I am referencing a part. Any fixes?

So I was debugging my script because I found countless others, I thought I hit the last one until this one came.

Workspace.mc:55: attempt to index nil with 'CFrame'

Here is the line of code giving me trouble.

player.Character.HumanoidRootPart.CFrame = game.Workspace.CurrentMap:WaitForChild("map_1", 7.5).CFrame + Vector3.new(0, 6, 0)

No, it is not the player.Character part. I added and deleted some stuff earlier to make sure it's the second part. Yes, the path is correct and it is a part, not a model.

Here is the function with the error:

function teleportPlayers()
    local t1 = true
    local t2 = false

    for i, player in pairs(game:GetService'Players':GetPlayers'') do
        if t1 == true then
            player.TeamColor = game.Teams.defend.TeamColor
            t1 = false
            t2 = true
            player.Character.HumanoidRootPart.CFrame = game.Workspace.CurrentMap:WaitForChild("map_1", 7.5).CFrame + Vector3.new(0, 6, 0)
        else
            player.TeamColor = game.Teams.attack.TeamColor
            t1 = true
            t2 = false
            player.Character.HumanoidRootPart.CFrame = game.Workspace.CurrentMap:WaitForChild("map_2", 7.5).CFrame + Vector3.new(0, 6, 0)
        end
    end
end

If needed, here is all of the code:

local players = game.Players:GetChildren()
local maps = game.Lighting:GetChildren()
local currentmap = game.Workspace:WaitForChild("CurrentMap")
local chosenmap = script:WaitForChild("ChosenMap")
local spawner1
local spawner2
local choices = {}
local status = game.ReplicatedStorage:WaitForChild("status")
local intermission


--choose map randomly
function chooseMap()
    for i = 1,#maps do
        if maps[i]:isA("Model") then
            table.insert(choices,maps[i])
        end
    end
    local picked = math.random(1,#maps)
    chosenmap.Value = tostring(picked)
end

--load map
function loadMap()
    local map = game.Lighting.Maps:FindFirstChild("map" .. chosenmap.Value)
    local mapnamelol = ("map" .. chosenmap.Value)
    print(mapnamelol)
    map:Clone().Parent = currentmap
end

--unload and delete
function unloadMap()
    for i,v in pairs(currentmap:GetChildren()) do
        if v:isA("Model") then
            v:Destroy()
        end
    end
end


local mapqw = game.Lighting.Maps:FindFirstChild("map" .. chosenmap.Value)

--tp
function teleportPlayers()
    local t1 = true
    local t2 = false

    for i, player in pairs(game:GetService'Players':GetPlayers'') do
        if t1 == true then
            player.TeamColor = game.Teams.defend.TeamColor
            t1 = false
            t2 = true
            player.Character.HumanoidRootPart.CFrame = game.Workspace.CurrentMap:WaitForChild("map_1", 7.5).CFrame + Vector3.new(0, 6, 0)
        else
            player.TeamColor = game.Teams.attack.TeamColor
            t1 = true
            t2 = false
            player.Character.HumanoidRootPart.CFrame = game.Workspace.CurrentMap:WaitForChild("map_2", 7.5).CFrame + Vector3.new(0, 6, 0)
        end
    end
end
--tp back
function teleportBack()
    for i,player in pairs(players) do
        player.TeamColor = game.Teams.Spectator.TeamColor
        player:LoadCharacter()
    end
end

--cycle it
while true do
    intermission = 10
    while intermission >= 0 do
        status.Value = ("Intermission (" .. intermission .. ")")
        wait(1)
        intermission = intermission - 1
    end
    wait(3)
    status.Value = ("")
    chooseMap()
    status.Value = ("Map: " .. chosenmap.Value)
    loadMap()
    status.Value = ("Loading Map")
    wait(1)
    teleportPlayers()
    wait(10)
    status.Value = ("Unloading Map")
    unloadMap()
    teleportBack()
    status.Value = ("Teleported Back")
end

Any help is appriciated.
