Empty body in retrofit 2

i have a scenario that when you do a PUT on a end point and get an OK http code 200, then you dont expect a body. However if the server returns a http code representing an error, it send a error json as a body.

How do i handle both cases? it seems you can only handle one of the other

@PUT("/path/to/get")
Call<Response<<Void>> getMyData(/* your args here */);

if i get a errorResponse body, it will obviously wont get the data response

or

@PUT("/path/to/get")
Call<Response<ErrorResponse>> getMyData(/* your args here */);

If the response is good then it tries to convert a body that has nothing and results to a java.io.EOFException: End of input at line 1 column 1 path $

Use ResponseBody for such case:

service.getMyData().enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        if (response.isSuccessful()) {
            gson.fromJson(response.body().charStream(), MyClass.class);
        } else {
            //Do something in case of error
        }
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {

    }
});
