Animation tool script won't work

[HearTheThing (Increstagator)]

I have a server script with the RunContext set to client, but this script isn’t working. I have another tool with this exact same script that works fine, but this one seems to not. The only thing in the dev console is “Attempt to index nil with :WaitForChild()”, but that doesn’t seem to matter since the other tool works fine.

local animation = script.Parent.Parent:WaitForChild("TabletAnimation")
local humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")
local animator = humanoid:WaitForChild("Animator")
local track = animator:LoadAnimation(animation)

script.Parent.Parent.Equipped:Connect(function()
	track:Play()
end)

script.Parent.Parent.Unequipped:Connect(function()
	track:Stop()
end)

script.Parent.Parent.Destroying:Connect(function()
    track:Stop()
end)

Any help would be appreciated.

does the tool have ‘RequiresHandle’ set to true? This might be causing the issue

[HearTheThing (Increstagator)]

Yes, but the other tool has it enabled aswell and it works fine.

Is the other one also a server script running under the client context?

[HearTheThing (Increstagator)]

Yes, it uses the exact same script except for the names, which are different

Working Tool:
local animation = script.Parent.Parent:WaitForChild("TabletAnimation")
local humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")
local animator = humanoid:WaitForChild("Animator")
local track = animator:LoadAnimation(animation)

script.Parent.Parent.Equipped:Connect(function()
	track:Play()
end)

script.Parent.Parent.Unequipped:Connect(function()
	track:Stop()
end)

script.Parent.Parent.Destroying:Connect(function()
    track:Stop()
end)

Non-Working tool:
local animation2 = script.Parent.Parent:WaitForChild("KitAnim")
local humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")
local animator = humanoid:WaitForChild("Animator")
local track = animator:LoadAnimation(animation2)

script.Parent.Parent.Equipped:Connect(function()
	track:Play()
end)

script.Parent.Parent.Unequipped:Connect(function()
	track:Stop()
end)

script.Parent.Parent.Destroying:Connect(function()
    track:Stop()
end)

Pretty sure I found the problem, the script isn’t running. Not sure why though. Does anyone know?
