Exhausted retries on 5xx HTTP status codes return the final HTTP Response object with statusCode 503 rather than throwing an exception.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

When retries on 5xx responses are exhausted, agent.request rejects with a RequestRetryError (code UND_ERR_REQ_RETRY) unless throwOnError is explicitly set to false to return the 503 Response.
Retries transient 503 responses for idempotent GET requests and resolves the subsequent 200 response
Non-idempotent POST requests that receive 503 are not retried by default and throw immediately on the first attempt
Composing interceptors.retry before interceptors.redirect places redirect on the outer layer, retrying failed target endpoints directly without re-requesting the initial redirect origin
