Invalid argument #1 to 'ipairs' (table expected, got string)

Help and Feedback Scripting Support
1

Hi, I am trying to do an audio search GUI but it shows the following error in the output:
invalid argument #1 to ‘ipairs’ (table expected, got string) - Client - LocalScript:12

Script:

local HttpService = game:GetService("HttpService")
local ReplURL = "#######"
local Key = "#######"

local function searchSound(Keyword: string)
	local response = HttpService:RequestAsync({
		Url = ReplURL .. "/searchaudio" .. "?Keyword=" .. Keyword .. "&Key=" .. Key,
		Method = "GET"
	})
	if response.Success and response.Body then
		return HttpService:JSONDecode(response.Body).data
	end
end

game.ReplicatedStorage.Search.OnServerInvoke = function(player, keyword)
	if string.len(keyword) > 0 then
		local result = searchSound(keyword)
		if result then
			return result
		end
	end
end
2

This script doesn’t contain the error, it’s coming from the local script.

In your for loop you’re passing a string instead of a table. As zyro said, this isn’t the right script.

Ok I noticed the problem is with JSONDecode but I don’t know how to fix it, this is what it prints:

Can you post the actual function regarding the loop and what you’re sending

LocalScript:

local Template = script.Parent.Parent.ScrollingFrame.TextButton

script.Parent.SearchButton.MouseButton1Click:Connect(function()
	if string.len(script.Parent.TextBox.Text) > 0 then
		for _, instance in pairs(script.Parent.Parent.ScrollingFrame:GetChildren()) do
			if instance:IsA("TextButton") and instance ~= Template then
				instance:Destroy()
			end
		end
		local result = game.ReplicatedStorage.Search:InvokeServer(script.Parent.TextBox.Text)
		if result then
			for _, asset in ipairs(result) do
				local newTemplate = Template:Clone()
				newTemplate.Text = asset.Name
				newTemplate.Parent = script.Parent.Parent.ScrollingFrame
				newTemplate.MouseButton1Click:Connect(function()
					game.SoundService.Sound.SoundId = asset.AssetId

Convert JSON to a Lua object (via HttpService:JSONDecode) before running statements on it.

I can see you already did this, but try to make sure ANY return statement in your module has JSONDecode executed.

I checked and JSONDecode ran, but it doesn’t seem to work.

Try testing JSONDecode in the console. It might help you debug your problem to get a solution :smiley:
