amazon-web-services - AWS Java SDK v2.10：删除成功时 QuickSightClient 抛出 SdkClientException

Question

quickSightClient.deleteUser(deleteUserRequest)引发空指针异常，因为它无法编组 204 No Content 响应，AWS Quicksight 在成功删除用户后返回该响应。

我的问题：

1. 有没有比使用 try/catch 吞下错误更好的方法来处理或避免这个问题（见下文）？
2. 我应该将此报告为他们的 GitHub 项目中的错误吗？我报告了这个GitHub 问题。

我的代码：

private void deleteQuickSightUser() {
    String awsAccountId = "..."
    String roleName = "cc-embedding_quicksight_dashboard_role"
    String email = "[e-mail]"
    String namespace = "default"
    String roleArn = "arn:aws:iam::$awsAccountId:role/$roleName"

    QuickSightClient quickSightClient = QuickSightClient.create()

    User user = quickSightClient.listUsers(ListUsersRequest.builder()
        .awsAccountId(awsAccountId)
        .namespace(namespace)
        .build()
    ).userList().find { it.email() == email }

    if (user) {
        log.error("found the $email user with username: $user.userName")
        DeleteUserRequest deleteUserRequest = DeleteUserRequest.builder()
            .awsAccountId(awsAccountId)
            .namespace(namespace)
            .userName(user.userName)
            .build()

        try {

            /* *** THE FOLLOWING LINE THROWS THE EXCEPTION *** */
            quickSightClient.deleteUser(deleteUserRequest)

        } catch (SdkClientException e) {
            log.error(e.message)
        }

        log.error("deleted user $user.email")
    }
}

例外

Answer 1

我认为您现在应该使用 try/catch 并将其报告为错误。堆栈跟踪是什么样的？
