Подскажите в чем ошибка, почему не могу извлечь данные?

Использую библиотеки retrofit. У меня структура JSON вот такая:

Вот мой интерфес :

@Headers({("X-Signature: reserved"),("Content-Type: text/x-json")})
@POST("get_routes")
Call <MyRoutes> getRoutes(@Body Map<String, String> id);

Вот мой retrofit:

Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("http://gps.alematics.com/") // Адрес сервера/
            .addConverterFactory(GsonConverterFactory.create()) // говорим ретрофиту что для сериализации необходимо использовать GSON
            .build();
jsonPlaceHolderApi = retrofit.create(JsonPlaceHolderApi.class);

Вот так звоню:

public void getRouteList() {
    Map<String, String> parameters = new HashMap<>();
    parameters.put("device_id", "1789fa18ad90ba55");
    Call<MyRoutes> call = jsonPlaceHolderApi.getRoutes(parameters);

    call.enqueue(new Callback<MyRoutes> () {
        @SuppressLint("SetTextI18n")
        @RequiresApi(api = Build.VERSION_CODES.N)
        @Override
        public void onResponse(Call<MyRoutes> call, Response<MyRoutes> response) {

 List<MyRoutes>rout=Collections.singletonList(response.body());
           
            if (!response.isSuccessful()) {
                Log.d("asd", "no" + response.errorBody());
                return;
            } else {
                EditText editText = findViewById(R.id.editText4);
                Log.d("asd", "" + myRoutes.getRoutes());
              

                    }
                


                }

        }
