The dataclass will be automatically converted to a Pydantic dataclass.

This way, its schema will show up in the API docs user interface:

`Header`는 `Path`, `Query` 그리고 `Cookie`가 제공하는 것 외에 기능이 조금 더 있습니다.

대부분의 표준 헤더는 "마이너스 기호" (`-`)라고도 하는 "하이픈" 문자로 구분됩니다.

그러나 파이썬에서 `user-agent`와 같은 형태의 변수는 유효하지 않습니다.

따라서 `Header`는 기본적으로 매개변수 이름을 언더스코어(`_`)에서 하이픈(`-`)으로 변환하여 헤더를 추출하고 기록합니다.

또한 HTTP 헤더는 대소문자를 구분하지 않으므로 "snake_case"로 알려진 표준 파이썬 스타일로 선언할 수 있습니다.

					},
					UserRequest: levent.UserRequest{
						Headers: map[string][]string{},
					},
					UserIdentity: levent.Identity{
						PrincipalID: "test-user",
					},
				}, nil
			}

			req := httptest.NewRequest("GET", "/objectlambda/"+bucketName+"/"+objectName+"?lambdaArn="+url.QueryEscape(lambdaARN), bytes.NewReader(body))

- In `Compliance` mode, objects cannot be deleted by anyone until retention period has expired for the given version id. If user has governance bypass permissions, an object's retention date can be extended in `Compliance` mode.
- Once object lock configuration is set to a bucket

- Creation and deletion of all IAM users, groups, policies and their mappings to users or groups
- Creation of STS credentials
- Creation and deletion of service accounts (except those owned by the root user)
- Changes to Bucket features such as:
  - Bucket Policies
  - Bucket Tags
  - Bucket Object-Lock configurations (including retention and legal hold configuration)
  - Bucket Encryption configuration
