무엇이 잘못될 수 있나요?​

API 요청이 실패하면 RPC 서버는 제한된 수의 잘 정의된 오류 변형과 함께 구조화된 오류 응답을 반환하므로, 클라이언트 코드는 가능한 모든 오류 사례를 철저하게 처리할 수 있습니다. JSON-RPC 오류는 오류 응답을 구조화하기 위해 verror 규칙을 따릅니다.

    "error": {
        "name": <ERROR_TYPE>,

무엇이 잘못될 수 있나요?​

API 요청이 실패하면 RPC 서버는 제한된 수의 잘 정의된 오류 변형과 함께 구조화된 오류 응답을 반환하므로, 클라이언트 코드는 가능한 모든 오류 사례를 철저하게 처리할 수 있습니다. JSON-RPC 오류는 오류 응답을 구조화하기 위해 verror 규칙을 따릅니다.

{
    "error": {
        "name": <ERROR_TYPE>,
        "cause": {
            "info": {..},
            "name": <ERROR_CAUSE>
        },
        "code": -32000,
        "data": String,
        "message": "Server error",
    },
    "id": "dontcare",
    "jsonrpc": "2.0"
}

주의

위 구조의 code, data, 및 message 필드는 레거시 항목으로 간주되며, 향후 사용되지 않을 수 있습니다. 이에 의존하지 마세요.

다음은 EXPERIMENTAL_protocol_config 메서드에 의해 반환될 수 있는 오류 변형의 전체 목록입니다.

  • 요청한 블록이 올바른지 확인하세요.
