Respuestas de ajuste retro se bloquean con pro guard

Tengo una aplicación que utiliza retrofit para llamadas de api. Estoy tratando de añadir protección pro, pero sigue fallando con una de las respuestas.

FATAL EXCEPTION: main Process: com.karriapps.smartsiddurlite, PID: 13387 java.lang.NullPointerException: Attempt to invoke interface method 'java.lang.Object java.util.List.get(int)' on a null object reference at com.karriapps.smartsiddur.util.b$3.a(SourceFile:255) at com.karriapps.smartsiddur.util.b$3.success(SourceFile:252) at retrofit.CallbackRunnable$1.run(SourceFile:45) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:135) at android.app.ActivityThread.main(ActivityThread.java:5431) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:914) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:707) 

Sé por un hecho que la respuesta contiene los datos, simplemente no parece ser capaz de deserializarlo

• RxJava y Retrofit - Aumento de excepciones personalizadas en función de la respuesta del servidor
• Usando retrofit con persistencia de Cookie
• Añadir Retrofit Requestinterceptor con Dagger en tiempo de ejecución
• Subir varias imágenes al servidor en una cola
• Mock Retrofit Observable <T> respuesta en las pruebas de la unidad Android

Aquí está el código que falla

 mElavationService.getElevation(new ElavationService.LatLng(mLocation.getLatitude(), mLocation.getLongitude()), BING_KEY, new Callback<BingElevationResponse>() { @Override public void success(BingElevationResponse bingElevationResponse, Response response) { double elavation = bingElevationResponse.getResourceSets().get(0) .getResources().get(0).getOffsets().get(0); if (elavation > 0) { mLocation.setElevation(elavation); } else { mLocation.setElevation(0); } responsesCount++; if (requestsCount == responsesCount) { setZmanimToLocation(mLocation); } } @Override public void failure(RetrofitError error) { Log.e(TAG, error.toString(), error.fillInStackTrace()); mLocation.setElevation(0); responsesCount++; if (requestsCount == responsesCount) { setZmanimToLocation(mLocation); } } }); 

Y mi archivo pro guard

Edit: He añadido la clase pojo en sí

 public class BingElevationResponse { private List<ResourceSet> resourceSets; public List<ResourceSet> getResourceSets() { return resourceSets; } public class ResourceSet { private List<Resource> resources; public List<Resource> getResources() { return resources; } } public class Resource { private List<Integer> elevations; public List<Integer> getOffsets() { return elevations; } } } 

Su camino es

 com.karriapps.smartsiddur.model.response.BingElevationResponse 

Apreciaría profundamente la ayuda de la hormiga Gracias
