Square Retrofit: Exception converting byte[] - exception

Question

I'm using Retrofit to get some data from my WebAPI REST service. However my model contains a byte[] and this leads to an exception.
The exception I receive looks like this:
Caused by: retrofit.converter.ConversionException: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 122 path $.Photo
This exception appears because my model has a byte[] called Photo.
My model:
public class Artists {
private long ID;
private String Firstname;
private String Lastname;
private String Description;
private String Countrycode;
private byte[] Photo;
private java.util.Date Born;
private java.util.Date Death;
private java.util.Date Edited;
My REST API Java interface:
public interface ArtistRestService {
#GET("/artist/{id}")
Artists getArtist(#Path("id") long artistID);
#GET("/artist")
List<IdEditedRestObj> getArtists();
}
I know that I could use retrofit.mime.TypedByteArray but I also use GreenDAO an ORM mapper and I do not feel like to refactor the whole stack.
Is there an simple workaround/solution so I can somehow parse the incoming json so that exception does no take place?

Solution found:
Using https://github.com/square/retrofit/blob/master/retrofit-converters/jackson/src/main/java/retrofit/converter/JacksonConverter.java
public RestService(String url){
restAdapter = new RestAdapter.Builder()
.setClient(new OkClient(getClient()))
.setEndpoint(url)
.setConverter(new JacksonConverter())
.setErrorHandler(new RetrofitErrorHandler())
.setLogLevel(RestAdapter.LogLevel.HEADERS_AND_ARGS)
.build();
}
Everything works fine now, thx
