GCP 在上传“debug-server”服务（模块）的版本之前更改应用引擎的“默认”服务（模块）

问：

我正在使用 Ap 引擎设置服务器端标记。我按照此处的官方文档按照步骤操作 https://developers.google.com/tag-platform/tag-manager/server-side/app-engine-setup 因此，我的 GCP 项目和我的 App 引擎都已创建。

然后，我按照以下 shell 脚本创建我的标记服务器bash -c "$(curl -fsSL https://googletagmanager.com/static/serverjs/setup.sh)"

但是在我完成所有提示后，我收到以下错误消息： 错误：（gcloud.app.deploy） INVALID_ARGUMENT：上传到新应用程序的第一个服务（模块）必须是“默认”服务（模块）。在上传“debug-server”服务（模块）的版本之前，请先上传“默认”服务（模块）的版本。

如何上传第一个“默认版本”？ 任何帮助将不胜感激。

以下是所有配置：

我尝试使用 Google Cloud App Engine 创建标记服务器。但是由于所述错误，创建过程未完成。
