I'm not sure if this is a LS issue, but after many tries and searches, I decided to post about my issue here.
I use node.js and lightstreamer-client-node module.
If I create a subscription :
mySubscription = new ls.Subscription(...);
and then I add listeners, for example :
onSubscription: function() {

I have noticed that node won't trigger any errors, and the callback will silently stop executing (without returning).
For example, with this code, with this unexistentFunction. Also, is the functions exists but inside the functions there are errors, the same will occur.
Any way to recover the normal behavior, triggering exception errors ?

Thank you in advance
