伊奥。grpc。StatusRuntimeException:从App Engine查询Secret Manager时超过了截止时间

Question

我正在尝试使用应用程序引擎应用程序中的listSecrets（）在Secret Manager中列出机密，但grpc请求在60秒后一直超时：

com.google.api.gax.rpc.DeadlineExceededException: io.grpc.StatusRuntimeException: DEADLINE_EXCEEDED: Deadline exceeded after 59.973305176s.

我验证了我可以使用应用引擎中的其他GCP服务，并且我的应用引擎默认服务号具有秘密管理器角色。我的应用程序是标准环境Java第二代应用程序。我使用的是的v23.0.0库-bom（最新的）。当我在本地运行时，同样的代码工作正常，不会超过几秒钟，所以我想知道这是应用引擎环境还是其服务号的问题。

更新：我最终使用了google api services secretmanager/google api client/google-auth-library-oauth2-http。这个截取在本地和应用程序引擎上运行良好。

var projectId = "<TODO>";
var credentials = GoogleCredentials.getApplicationDefault();
var secretManager = new SecretManager.Builder(
        new NetHttpTransport(),
        new GsonFactory(),
        new HttpCredentialsAdapter(credentials))
        .build();

ArrayList<Secret> secrets = new ArrayList<>();
String pageToken = null;
do {
    var response = secretManager.projects().secrets().list("projects/" + projectId)
            .setPageToken(pageToken)
            .execute();
    pageToken = response.getNextPageToken();
    secrets.addAll(response.getSecrets());
} while (pageToken != null);

我终于看了日志（不仅仅是例外），看到了这个

java.lang.IllegalStateException: Could not find policy 'pick_first'. Make sure its implementation is either registered to LoadBalancerRegistry or included in META-INF/services/io.grpc.LoadBalancerProvider from your jar files.
    at io.grpc.internal.AutoConfiguredLoadBalancerFactory$AutoConfiguredLoadBalancer.<init>(AutoConfiguredLoadBalancerFactory.java:92)
    at io.grpc.internal.AutoConfiguredLoadBalancerFactory.newLoadBalancer(AutoConfiguredLoadBalancerFactory.java:63)

    ...

这导致了Stackoverflow帖子和Github问题。

我的构建使用Maven Shade插件。两个工件，io。grpc:grpc grpclb，和io。grpc:grpc核心有一个META-INF/services/io。grpc。LoadBalancerProvider文件，但我想要的是grpc核心。在我的阴影配置中添加一个排除项修复了它：

<filter>
    <artifact>io.grpc:grpc-grpclb</artifact>
    <excludes>
        <exclude>META-INF/services/io.grpc.LoadBalancerProvider</exclude>
    </excludes>
</filter>
