GCP 日志记录和云跟踪 API 返回 503 UNAVAILABLE 错误

问：

我是GCP云服务的新手，我正在尝试为Spring Boot存储库之一设置云日志记录/跟踪，因此我正在使用Spring Boot云GCP库来执行相同的操作。

我尝试在我的本地开发环境中运行该服务，我已经将GOOGLE_APPLICATION_CREDENTIALS文件位置设置为应用程序的环境变量。我已确保服务帐户具有正确的角色集，用于将日志和跟踪写入 GCP 操作套件 （stackdriver）。

但是，我注意到我收到了 cloudtrace.googleapis.com 和 logging.googleapis.com REST/grpc 调用的 503 UNAVAILABLE 响应状态。

我已经确保，通过使用下面的gcloud CLI命令，为我的项目启用了上述两个API。

gcloud 服务支持 cloudtrace.googleapis.com

gcloud 服务支持 logging.googleapis.com

当我尝试通过 gcloud cli 插入日志时，它按预期工作。

这些是作为 DefaultCredentialsProvider 配置的一部分设置为的凭据范围 -

[https://www.googleapis.com/auth/bigquery, https://www.googleapis.com/auth/trace.append, https://www.googleapis.com/auth/logging.admin, https://www.googleapis.com/auth/sqlservice.admin, https://www.googleapis.com/auth/devstorage.read_only, https://www.googleapis.com/auth/monitoring.write, https://www.googleapis.com/auth/pubsub, https://www.googleapis.com/auth/logging.write, https://www.googleapis.com/auth/spanner.admin, https://www.googleapis.com/auth/cloudruntimeconfig, https://www.googleapis.com/auth/devstorage.read_write, https://www.googleapis.com/auth/cloud-platform, https://www.googleapis.com/auth/spanner.data, https://www.googleapis.com/auth/datastore, https://www.googleapis.com/auth/cloud-vision]

请在下面找到用于设置应用程序的示例 java 配置。
