Internal error in Firestore (0.6.6-dev)

이미지를 firestorage에 올릴 때 해당 에러가 발생하면서 앱이 강제 종료 되었다
stack over flow나 여러곳을 찾았지만 원인을 알 수 없었다
해당 프로젝트는 instagram 클론 프로젝트 인강을 따라하고 있는 중이었다. 그래서 gradle에서 포함한 라이브러리를 강의와 똑같이 만들었다
com.google.code.gson:gson:2.8.6
com.google.http-client:google-http-client:1.34.0
com.google.http-client:google-http-client-android:1.34.0
com.google.http-client:google-http-client-gson:1.34.0
위 라이브러리 삭제
그리고 나서 해당 에러가 없어졌다. 아마 라이브러리끼리 무언가 충돌이 일어난 듯 하다
