rx java retrofit 2 error handling

Question

I\'m using retrofit 2 along with rx java

Situation: the app sends some request, then i get the response in json-format that is automatically converted to User dto,

Answer 1

I had the same situation and the way I could get the json from the server when an error occurs was something like this:

retrofit2.Response r = call.execute();

String errorMessage = "";
try {
    errorMessage = r.errorBody().string();
} catch (IOException e) {
    e.printStackTrace();
}
Timber.d("errorMessage: " + errorMessage);
