Panic on request

[Johnathan]

Similar to #7 and #4

Issue happens when I make a GET request to /ping

init.lua

espress = require 'espress'

function initialConnection()
    wifi.setmode(wifi.STATIONAP)

    -- Setup as Access Point
    wifi.ap.config({
        ssid = "Hame-Hue-Switch",
        pwd = "hamepassword",
        auth = wifi.OPEN
    })

    local server = espress.createserver();

    server:use("routes_auto.lc")

    server:listen(80);
end

initialConnection()

routes/ping.get.lua

return function(req, res)
    res:addheader("Content-Type", "application/json; charset=utf-8")
    res:send("{device: \Light Switch\"}")
end

Just realised I should be hitting /api/ping, when I do that it's loading my route file ok, but it seems to be after that the panic occurs but slightly different this time

Error occured during execution: bad argument #2 to 'on' (function or lightfunction expected, got nil)
PANIC: unprotected error in call to Lua API (bad argument #2 to 'on' (function or lightfunction expected, got nil))

Hi @Johnathan , I see you are using an old version of NodeMCU.
Would you be able to upgrade to NodeMCU 2.X?

[Johnathan]

Yep, that's it sorted now sorry. I mistook the version of the library for the supported version of nodemcu.

Thanks for the speedy reply

[loicortola]

No worries! Glad I could be of help. Have fun with the library, your feedback is welcome if you like it!
