(Solved)Does the for loop not work with the GetPlayers to recognize the player?

Well, that I do not go for the loop with GetPlayers () I give debug and jump to the end and stop. I've tried a simple for loop and it works.

local PathfindingService = game:GetService("PathfindingService")
local Players = game:GetService("Players"):GetPlayers()
local enemy = script.Parent
local humanoidEnemy = enemy.Humanoid
local humanoidRootPart = enemy.HumanoidRootPart
local Start = script.Parent.Parent.Start
local Finish = script.Parent.Parent.Finish
local currentDestination = Start

for i , player in pairs(Players) do
	local character = game.Workspace:WaitForChild(player.Name)
	print(player.Name)
	if character then
		while wait(1) do
			local mag = (character.Head.Position - enemy.Head.Position).magnitude			
			if mag <= 50 then
				print("Attack")
			else
				print(mag)
					
				while wait(2) do
					local startingPosition = humanoidRootPart.Position
					local goalPosition = currentDestination.Position
					local path = PathfindingService:FindPathAsync(startingPosition, goalPosition)
					local waypoints = path:GetWaypoints()
					for waypointIndex, waypoint in pairs(waypoints) do
						local waypointPosition = waypoint.Position
						humanoidEnemy:MoveTo(waypointPosition)
						humanoidEnemy.MoveToFinished:Wait()
					end	
					if currentDestination == Start then
						currentDestination = Finish
					else
						currentDestination = Start
					end
											
				end
			end
			
		end
	end
end

Thank you, thank you very much, now I have the problem that it does not calculate the distance while advancing it stays in the distance from the beginning.

while true do
			local mag = (character.Head.Position - enemy.Head.Position).magnitude			
			if mag <= 50 then
				print("Attack")
			else
				print(mag)
					
				while wait(2) do
					local startingPosition = humanoidRootPart.Position
					local goalPosition = currentDestination.Position
					local path = PathfindingService:FindPathAsync(startingPosition, goalPosition)
					local waypoints = path:GetWaypoints()
					for waypointIndex, waypoint in pairs(waypoints) do
						local waypointPosition = waypoint.Position
						humanoidEnemy:MoveTo(waypointPosition)
						humanoidEnemy.MoveToFinished:Wait()
					end	
					if currentDestination == Start then
						currentDestination = Finish
					else
						currentDestination = Start
					end
											
				end
			end
			wait()
		end
