Pcall is broken and not reading my function?

I made multiple pcalls before and they work, but nowdays they dont work. Here is one of my scripts I was making with someone else.

local s, m = pcall(FindPlayer())
	if s then
		--stuff
	else
		warn('Attempted to add "'..plr:GetFullName()..'" to the list!')
	end

The function:

function FindPlayer()
	game.Players:GetPlayerFromCharacter(plr)
end

The error says

ServerScriptService.MainScript:68: bad argument #1 to 'pcall' (function expected, got no value)

even though it is a function.
