whateverString class를 못찾는 에러가 발생한다

프로젝트 빌드가 되지않을정도의 치명적 에러는 아닌데 계속 뜨니까 불안해서 고치려고 시도했다

Unresolved reference:enqueue

자꾸 enqueue 함수를 못찾았는데,, 반환형을 Call로 선언해주지않아서 생기는 오류였다

Kotlin-android unresolved reference : queue

서버 통신은 성공했으나 body값이 null값으로 날라올때 /   java.lang.NullPointerException

통신도 성공하고 body값도 날라오는데.. null pointer 에러가 뜨면서 body값이 없다고 날라왔다

그 이유는 아래에 있다,,

@SerializedName 파라미터값이 곧 받아와지는 response body field 명인데 이를 수정해주지않아서 생겼던 어이없는 실수,..였다

가급적이면 실기기로  테스트하자..
