Yes. I get same error as the original post when I use cosock http

Below is the code, which fails to parse the Awair’s http response

local cosock = require "cosock"
local socket = require "cosock.socket"
local http = cosock.asyncify "socket.http"
local ltn12 = require "ltn12"
local json = require "st.json"
local utils = require "st.utils"
local log = require "log"

local function http_get(url)
	local host, path = string.match(url, "http://([^/]+)(/.*)")
	local res_body = {}
	local _, code = http.request({
			method="GET",
			url=url,
			sink=ltn12.sink.table(res_body),
			headers={
			["HOST"] = host,
			["Connection"] = "close"
		},
	})
	log.debug('[http response code] '..code)
	log.debug('[http response body] '..utils.stringify_table(res_body))
	return res_body, code
end

-- below is how you use this http_get function.
local air_json, err = http_get(device.preferences.url..'/air-data/latest')

and below is the hub log (with hub version 45.11)

I’ve already posted raw TCP data from the Awair device, which fails to be parsed with the built in cosock http libaray.
