안녕하세요. klaytn ide에서 test 할 때는 잘 돌아가는데 caver로 넘어와서 실행하면 Error: evm: execution reverted 나오는데 어디가 문제인지 모르겠습니다. smart-contract는 truffle 이용해서 배포했습니다.

안녕하세요

evm reverted의 원인을 분석하기 위해서는 debug API를 사용해야 합니다.  
혹은 아래와 같이 [Scope](https://baobab.scope.klaytn.com/tx/0x0c09b6a03ee6db649322acfb6169ceb2bbba7cb042038bbf9e91dedd82690381?tabId=internalTx)에서 failure의 원인을 조회할 수도 있습니다.

참고 부탁드립니다.
