에러메세지 레퍼런스를 보면
https://firebase.google.com/docs/reference/unity/class/firebase/storage/storage-exception#class_firebase_1_1_storage_1_1_storage_exception_1a6325f13b8c24f6380f533e40eb0773ea

Firebase.Storage.StorageException Class Reference

빨간색으로 표시한 에러가 UnKnownError 라고 뜸 어이없음 ???

해결

string PathSt = "";
#if UNITY_EDITOR
PathSt = Path.Combine(Application.streamingAssetsPath);
#else
PathSt = Application.persistentDataPath;
#endif

유니티에디터랑 모바일에서의 로컬파일 저장 경로를 다르게 설정해줘야 함.
Set different saving local path for build version
처음부터 레퍼런스에 이렇게 써놓으라고요.
Couldn't  they just write it on the reference together?

언젠가 빌드해야할 프로젝트인데 유니티용만 써놓으면 어떡하냐고


일단 안드로이드 빌드 성공했고 iOS 는 내일 되는지 확인하기로.
