[Help] esx_shops error - attempted to index a nil value (global 'ESX')

[Niteshadez]

Hey all,

Let me start by saying I’m VERY new to this. However, I’ve been struggling with this error. I’ve done some research and what I’ve found here, I’ve already done. Looking for more input. Any is appreciated!

Thank you!

"Error loading script client/main.lua in resources esx_shops: @esx_shops/client/main.lua:50 attempt to index a nil value (global ‘ESX’)

Here’s my script.

MySQL executions should be always at server side (server.lua or main.lua contained inside a server folder). Try to call it from server side and pass the info you want to the client with an event.

If you have a resource trigger scrambler, then it would the esx:getSharedObject would be scrambled, leaving the script to be not useable. I had this issue until I changed my getSharedObject to my scrambled one.

It might be that MySQL ready ups and queries faster than ESX returns the shared object to you.

Change:

-- is the player trying to exploit?
	if amount < 0 then
		print('esx_shops: ' .. xPlayer.identifier .. ' attempted to exploit the shop!')
		return
	end

To

	if amount < 0 then
		print('esx_shops: ' .. xPlayer.identifier .. ' attempted to exploit the shop!')
		return
	end
end
