Can't Parse JSON?

I get the error “Can’t Parse JSON” in the output. I have a string value for a datastore that I reference from by using the JSON encode/decode method so I can save a multiple things from my character customization system into 1 string.

local function updateViewPort(build_data)
	--//Load Current Stats (Stamina/Power)\\
	if build_data == "Build_Data1" then
		current_Edits.Stamina.Value = Data_Folder:FindFirstChild("Stamina").Value
	elseif build_data == "Build_Data2" then
		current_Edits.Stamina.Value = Data_Folder:FindFirstChild("Stamina2").Value
	elseif build_data == "Build_Data3" then
		current_Edits.Stamina.Value = Data_Folder:FindFirstChild("Stamina3").Value
	end
	
	
	local build = Data_Folder:FindFirstChild(script.Parent.Build_Slot.Value)

	if build then
		local decodedData = game:GetService("HttpService"):JSONDecode(build.Value)
	

this is called by this function

script.Parent.Build_Slot:GetPropertyChangedSignal("Value"):Connect(function()
	
	if script.Parent.Build_Slot.Value ~= '' then
		updateViewPort(script.Parent.Build_Slot.Value)
	end
end)

The Built_Slot.Value is the name of the datastore String Value.
