On startup require does not load json.lua

[tiago138]

On startup the require json does not work, but if I run conky from the terminal it works.
Anyone has an idea of what may be happening?
Thanks.

local function getCoinData(cr)
	local json_status, json = pcall(require, "./json")
	if not json_status then
		write(cr, 100, 718, "not", 18, color0, fg_alpha)
    return
	end

	local open = io.open
	local file_data = open("data.json", "rb")

	if file_data == nil then
		write(cr, 100, 718, "aqui", 18, color0, fg_alpha)
		return
	end

	local jsonString = file_data:read("*a")
	file_data:close()
	local t = json.decode(jsonString)

	local price = t.data["17587"].quote.USD.price

	write(cr, 100, 718, "" .. round(price, 6) .. "", 18, color0, fg_alpha)
end
