Retrofit: Custom ConverterFactory answer only

I have a general response from the server:

{
  "Error": null,
  "Data": {}
  }
}

      

        
        
        
      

    

So, I created my own factory converter to get the object inside Data

.

The main idea is to change:

• this Call<ResponseBase<List<Item>>> getItems();
  
  
• to Call<List<Item>> getItems();
  
  

It works fine with responses, but when I try to send and the object in the request with @Body

, the converter fails ...

java.lang.IllegalArgumentException: Unable to create @Body converter for class <package>.data.entities.request.RequestLogin (parameter #1)
...     
Caused by: java.lang.IllegalArgumentException: Could not locate RequestBody converter for class <package>.data.entities.request.RequestLogin.
        Tried:
             * retrofit2.BuiltInConverters
             * <package>.data.api.ResponseConverterFactory

      

        
        
        
      

    

This is my custom one Converter.Factory

:

class ResponseConverterFactory extends Converter.Factory {

    // constructor

    @Override
    public Converter<ResponseBody, ?> responseBodyConverter(final Type type, Annotation[] annotations, Retrofit retrofit) {
        Type wrappedType = new ParameterizedType() {
            @Override
            public Type[] getActualTypeArguments() {
                return new Type[] {type};
            }

            @Override
            public Type getOwnerType() {
                return null;
            }

            @Override
            public Type getRawType() {
                return ResponseBase.class; // GENERIC CLASS
            }
        };

        Converter<ResponseBody, ?> converter = factory.responseBodyConverter(wrappedType, annotations, retrofit);
        return new ResponseConverter(converter);
    }

}

      

        
        
        
      

    

How can I use the default converter to serialize the request?
