I'm using Retrofit 2.0.0-beta1.

In tests i have an alternate scenario and expect error HTTP 400

I would like to have retrofit.Response<MyError> response but response.body() == null

MyError is not deserialised - i see it only here

response.errorBody().string()

but it doesn't give me MyError as object

I currently use a very easy implementation, which does not require to use converters or special classes. The code I use is the following:

public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
    DialogHelper.dismiss();

    if (response.isSuccessful()) {
        // Do your success stuff...
    } else {
        try {
            JSONObject jObjError = new JSONObject(response.errorBody().string());
            Toast.makeText(getContext(), jObjError.getJSONObject("error").getString("message"), Toast.LENGTH_LONG).show();
        } catch (Exception e) {
            Toast.makeText(getContext(), e.getMessage(), Toast.LENGTH_LONG).show();
        }
    }
}
