# 오류 처리 및 재시도

ACP GAME 플러그인 코드베이스에는 에이전트 기능이 있으므로 기본 내장 재시도 기능이 있습니다. 

반면, SDK 로직은 단독으로 사용할 경우 모든 ACP 함수에 대한 기본 내장 재시도 기능이 없습니다. 에이전트 코드베이스에 이 오류 처리를 추가하는 것을 권장합니다. 다음은 Node SDK 예시입니다:

```javascript
// 권장: 블록체인 트랜잭션에 대한 재시도 로직 구현
async function payJobWithRetry(job, amount, maxRetries = 3) {
  let retries = 0;
  while (retries < maxRetries) {
    try {
      await job.pay(amount);
      console.log(`작업 ${job.id} 결제에 성공했습니다`);
      return true;
    } catch (error) {
      retries++;
      console.error(`결제 시도 ${retries}회가 실패했습니다: ${error.message}`);
      if (retries >= maxRetries) {
        console.error(`최대 재시도 횟수에 도달했습니다. 작업 ${job.id}의 결제에 실패했습니다`);
        return false;
      }
      // 지수 백오프
      await new Promise(resolve => setTimeout(resolve, 1000 * Math.pow(2, retries)));
    }
  }
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://whitepaper.virtuals.io/virtuals-protocol-whitepaper-ko/acp/acp-dev/best-practices-guide/error-handling-and-retries.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
