Image upload upgrade gives error

Question

Image upload upgrade gives error

I am trying to upload an image using the Retrofit library, but cannot find success in this;

Here is my code:

File photo = new File(picturePath);
    TypedFile typedFile = new TypedFile("multipart/form-data", photo);
    GroupTravelServer serverObject = Utils.getRetroFitAdapter();
    serverObject.uploadImage(Utils.getAuthHeader(getActivity()), "multipart/form-data", tripId,
            typedFile, new Callback<ChatMessageModel>() {
        @Override
        public void success(C

Here is my interface method:

@Multipart
@POST("/v1/messages")
void uploadImage(@Header(PARAM_AUTHORIZATION) String authorization,
                 @Header(PARAM_CONTENT_TYPE) String contentType, @Part("tripId") String tripId,
                 @Part("image") TypedFile image, Callback<ChatMessageModel> callback);

This is the path that was passed:

picturePath=  /storage/extSdCard/DCIM/Camera/2014-05-19 17.15.43.jpg

I get 500 internal server errors

with the following stacktrace:
