이슈
retrofit2.DefaultCallAdapterFactory$ExecutorCallbackCall@dffd7f3
com.google.gson.JsonIOException: JSON document was not fully consumed.
 
원인
REST API 의 Response 형태가 json 형태가 아닌 String 형태로 내려올 경우에 발생한다.
 
 
해결
ScalarsConverterFactory 추가
.addConverterFactory(ScalarsConverterFactory.create())
 
Retrofit.Builder()
    .baseUrl(IhpUrl.rest_api_url)
    .addConverterFactory(ScalarsConverterFactory.create())
    .addConverterFactory(GsonConverterFactory.create(gson))
    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
    .build();
ScalarsConverterFactory 는 Response 형태가 구조를 갖춘 json 형태가 아닌 string 형태로 받을 때 사용하는 컨버터
- 응답값을 String 형태로 받을 때 사용
