handler problem

[tempetum]

Hi

First of all, your node is really great, I can finally send direct orders to my bose Soundtouch.
The only problem I have, is to change the music from spotify. it crashes when i send the parameters.

I got this error:
Selecting to play new music source
/home/pi/SoundTouch-NodeJS/api.js:368
handler(json);
^

TypeError: handler is not a function

My URL sent is

http://10.10.22.52:5006/diningroom/select/SPOTIFY/*****/spotify:track:4TfnvCrnjbXYu8XrjC4yF1

but it crashes all the time. I have a reaction on the Ipad that want to change the song but the node crashes and nothing happen.

Do you have an idea from what it could be ?

Thank you
