I Recommend To Parent The Tool Instead Of Using EquipTool()

[AxeMurder24 (AxeMurder)]

If You Trying To FindFirstChild() Or WaitForChild() Something Inside The Tool, It’ll Make an Error Like This

I Rather Use Tool.Parent Than EquipTool(Tool)

I Hope It Helps!

Attempt to index nil with 'FindFirstChild'

Backpack is nil, thus you can’t run “FindFirstChild”. It’s possible that Backpack may have not replicated yet, thus trying to index/access “FindFirstChild” from a non-existent object, which is supposed to be a Backpack object.

The solution you have provided is not a fix or actual recommendation, but rather, a misunderstanding. Please analyse your code properly, thoroughly, and logically before making conclusions. As the above person said, EquipTool has a purpose.

Assuming all variables are readied, this is the fix:

local Player -- I assume Backpack is the Backpack object under a Player.
local Backpack = Player:WaitForChild("Backpack")

local ToolName = "Sword"
local Tool = Backpack:FindForChild(ToolName)

if Tool == nil then
	error(`{ToolName} is not a valid Tool.`)
end

Humanoid:EquipTool(Tool)

A working, complete, server-side example (under ServerScriptService):

local function WaitForChildWhichIsA(parent : Instance, className : string, timeOut : number?)
	if parent == nil or (not (typeof(parent) == "Instance")) then
		error("Parent not provided or is not an object.")
	end

	if className == nil or (not (typeof(className) == "string")) then
		error("Class name must be a string")
	end

	local ChildFound = parent:FindFirstChildWhichIsA(className)

	if ChildFound == nil then
		local RunService = game:GetService("RunService")
		local Deadline = tick() + (timeOut or 0)

		repeat
			RunService.Heartbeat:Wait()
			ChildFound = parent:FindFirstChildWhichIsA(className)
		until ChildFound or (if timeOut ~= nil then tick() > Deadline else false)
	end

	return ChildFound
end

local Players = game:GetService("Players")
local CharacterAddedConnections = {}

Players.PlayerAdded:Connect(function(Player)
	CharacterAddedConnections[Player] = Player.CharacterAdded:Connect(function(New_Character : Model)
		local Backpack = Player:WaitForChild("Backpack")
		
		local Humanoid : Humanoid
		local Character = Player.Character do
			if not Character then
				Character = Player.CharacterAdded:Wait()
			end
		end

		Humanoid = WaitForChildWhichIsA(Character, "Humanoid", 10)
		
		local ToolName = "Sword"
		local Tool = Backpack:FindFirstChild(ToolName)

		if Tool == nil then
			error(`{ToolName} is not a valid Tool.`)
		end

		Humanoid:EquipTool(Tool)
	end)
end)

Players.PlayerRemoving:Connect(function(Player)
	CharacterAddedConnections[Player]:Disconnect()
	CharacterAddedConnections[Player] = nil
end)

Edits

1. Fixed code display of server-side example.
2. Added more explanation as to how Backpack = nil happens.

This should go into #resources:community-tutorials

Not exactly if the given information doesn’t actually solve a problem.

Oh, sorry for my mistake

That is unfortunately not how it works. If you are able to read and understand what the error means then you’ll understand that your recommendation of using a different method to relocate the Tool to a character is completely irrelevant.
