Panic on request about nodemcu-espress

[Johnathan]

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

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