javascript - Firestore 导出 Cron 作业未运行：错误代码 204

Question

预期的

当部署的 Cron 作业在 GCP 上运行时，定义的 Firebase Cloud Storage 目录gs://my-project-name.appspot.com/将填充my-project-name's Firestore 数据库中的所有集合，实施后跟调度数据导出文档。

观察到的

Cron 作业部署成功，但运行失败。日志显示Error code 204。

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.

A problem was encountered with the process that handled this request, causing it to exit. This is likely to cause a new process to be used for the next request to your application. (Error code 204)

配置

1. GCP 和 Firebase 项目均启用了结算功能。
2. Firebase 存储桶当前已创建并用于在名为content的目录下存储mp3和txt文件，并创建了一个名为backups的新空目录以存储导出 Cron 作业的结果。

3. 已按照配置访问权限部分中的建议启用了以下权限。

4. GCP 项目被定义为default。

5. app.yaml和app.js代码已按原样复制。

6. 对于package.json，name、version和description属性已针对项目进行了更改。

7. 在cron.yaml中description和url属性是自定义的。url已尝试以下操作以导出所有集合：

   • /cloud-firestore-export?outputUriPrefix=gs://[my-project-name].appspot.com/backups

尝试的解决方案

1. 版本代码：在后续部署中增加版本代码。
2. cron.yaml网址：
   • 在目录之后添加/：/cloud-firestore-export?outputUriPrefix=gs://[my-project-name].appspot.com/backups/
   • 添加collections查询但将其留空：/cloud-firestore-export?outputUriPrefix=gs://[my-project-name].appspot.com/backups&collections
3. IAM 权限：将Cloud Datastore Import Export Admin权限添加到我的用户帐户[e-mail]，因为这是与 下的项目关联的电子邮件帐户gcloud config configurations list。

Answer 1

问题是package.json版本不能低于1.0.0. 我试图使用0.16.0. 我正在向文档团队发送一条说明，并且这应该包含在文档中以节省人们的时间。
