Deference of 'response.body()' may produce 'java.lang.NullPointerException

I have a error. name is value string type. setText is string type but i have a error.

     Factory.getInstance().placeHolderModel().enqueue(new Callback<PlaceHolderModel>() {
        @Override
        public void onResponse(Call<PlaceHolderModel> call, Response<PlaceHolderModel> response) {
            textView.setText(response.body().name);
        }
