현재 컨트렉트는 메인넷에 잘 배포되어있습니다.  
위와 같은 에러는 어떠한 상황에서 나오는건가요?

배포된 컨트렉트 주소는 다음과 같습니다.

컨트렉트 코드는 다음과 같습니다.  
pragma solidity ^0.4.25;

contract Withdraw {  
address public owner;

```auto
constructor(address _owner) public {
    owner = _owner;
}

function deposit() public payable {

}

function withdraw(uint256 amount) public {
    require(msg.sender == owner);
    owner.transfer(amount);
}

function getBalance() public view returns (uint256) {
    return address(this).balance;
}

```

}

그리고 abi는 3가지 형식으로 테스트 했는데, 아직까지 같은 에러가 발생중입니다.

빠른 답변 감사드립니다.

Sung-Bin Ahn님, 안녕하세요 🙂

혹시 내부에서 테스트해볼 수 있도록 실제 호출하신 Klip API 예제를 curl 스크립트로 전달해주시면 분석에 도움이 되겠습니다. 참고로 abi에는 실제로 호출하실 한 개의 메소드에 대한 abi를 넣어주셔야합니다.
