Describe the problem

There is no description anywhere on how to handle errors when subscribing. In my app, sometimes subscriptions don't work, and I have no idea on how to handle that. There is a channel.onError method, but it doesn't provide any error. So what should I do in the case subscriptions don't work?

Bump. Quite important for handling channels properly, and as of yet I've not been able to find out how to handle channel errors.
