Error Handling

Table of contents


When an error occure during SDK functionality, the error is passed to the hosting app, unless can be managed internaly.
Errors can raise due to connection problems, missuse, and many other reasons. Errors are passed to the hosting app via ChatEventListener.onError implementation.
Error events passes objects of NRError which defines the error that occured. The NRError consist of code, reason, description, and sometimes contains some extra data.

        .chatEventListener(object : ChatEventListener{
            override fun onError(error: NRError) {
                // handle error
