How do I award all players a badge?

Hi. I have a boss, and I want it to award everyone a badge when it is killed. I have the script for when it dies, but I don't know how to award everyone the badge. My script is below.

local humanoid = script.Parent

		humanoid.Died:Connect(function()
			print("woah")
			end)

local humanoid = script.Parent
local badgeID = 000000000 --Replace with your badge ID
humanoid.Died:Connect(function(plr)
	local a = game.Players:GetChildren()
	for i = 1,#a do
		if game:GetService("BadgeService"):UserHasBadgeAsync(a[i].UserId, badgeID)
			
		else
			game:GetService("BadgeService"):AwardBadge(a[i].UserId, badgeID)
		end
	end
end)

When your boss dies, the script will get all the players in the server, and award them the badge.
