Hey, i am new to httpsservice and i want to learn, as of now i am trying to save my avatar’s appearance and load it again when i join, but for some reason when i decode it, it returns a table and not a string. i may be dumb and do one real clear rookie mistake

_G.CanChangeAvatar = true
local HttpService = game:GetService("HttpService")
local AvatarStore = game:GetService("DataStoreService"):GetDataStore("AvatarStore")
game:GetService("Players").PlayerAdded:Connect(function(plr)
	if AvatarStore:GetAsync(plr.UserId.. "HumanoidSave") then
		print("it has saved")
		task.wait(5)
		local humjson = AvatarStore:GetAsync(tostring(plr.UserId) .. "HumanoidSave")
		print("turning json into thing")
		local humanoidtable = HttpService:JSONDecode(humjson)
		print(humanoidtable)
		local humDescription = Instance.new("HumanoidDescription")
		for property, value in pairs(humanoidtable) do
			humDescription[property] = value
		end
		workspace.Rig.Humanoid:ApplyDescription(humDescription)
		print("ah dammnit")
		return
	end
	task.wait(15)
	if _G.CanChangeAvatar then
		local appearance = game:GetService("Players"):GetHumanoidDescriptionFromUserId(plr.UserId)
		local HumDescTable = {
			BodyTypeScale = appearance.BodyTypeScale,
			DepthScale = appearance.DepthScale
		}
		local humanoidDescriptionJSON = HttpService:JSONEncode(HumDescTable)
		print(humanoidDescriptionJSON)
                                                  		AvatarStore:SetAsync(tostring(plr.UserId) .. "HumanoidSave", humanoidDescriptionJSON)
		workspace:WaitForChild("Rig"):FindFirstChildWhichIsA("Humanoid"):ApplyDescription(appearance)
		local Animation = Instance.new("Animation", workspace:FindFirstChild("Rig"))
		Animation.Name = "DanceAnim"
		Animation.AnimationId = "rbxassetid://18711469609"
		local loadanim = workspace.Rig.Humanoid:LoadAnimation(Animation)
		loadanim:Play()
	end
end)
