Retrofit @Part Multipartbody.Part with @multipart throws exception

I am implementing this question Retrofit @body with @multipart having Issue. Everything works great. Problem arises while adding @Part MultipartBody.Part file. It throws Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $. I would appreciate any help.

NOTE: I am using custom converterFactory and Interceptor (by implementing Gson). Could that be problem?
