    }

I don't see that you configured Gson correctly. Somethere in your code should be similar initialization:

Gson gson = new GsonBuilder()
    .setExclusionStrategies(new ExclusionStrategy() {
        @Override
        public boolean shouldSkipField(FieldAttributes f) {
            return f.getDeclaringClass().equals(RealmObject.class);
        }

        @Override
        public boolean shouldSkipClass(Class<?> clazz) {
            return false;
        }
    })
    .create();

Look at the documentation for more details: https://realm.io/docs/java/latest/#gson
