Somebody know how can I fix it ?
Thank you

It appears you have a null exception added to a composite somewhere. What operators are you using. Do you call onError(null) somewhere by accident?

I try to get throwable.getMessage callback and have this null pointer.
I already find the reason. I make mistake at URL and try to connect to non-existent URL. I changed it and all is fine.
I think you need handle this null pointer in other way, because currently I can't normally find the reason of exception.
Thank you
