In java this works fine

.flatMap(response -> {
         if (!response.isSuccessful()) {
             ResponseBody errorBody = response.errorBody();
             if (errorBody == null) {
                return Single.error(new IllegalStateException("Error response body is null"));
             }
         }
         return Single.just(response);
});
