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. 已为GCP和Firebase项目启用了计费。
2. 当前已创建Firebase存储桶，并将其用于将 mp3 和 txt 文件存储在名为 content 的目录下，并具有新的空目录创建名为 backups 的文件来存储导出Cron作业的结果。

1. 已按照 Schedule data exports 部分中的建议启用了以下权限。

1. GCP项目定义为默认。

2. Configure access permissions 和 app.yaml 代码已被复制。

3. 对于 app.js ，name，version和description属性已针对项目进行了更改。

p>

4. 在 package.json 中，description和url属性是自定义的。对于url，尝试了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/后添加/cloud-firestore-export?outputUriPrefix=gs://[my-project-name].appspot.com/backups/
   • 添加collections查询，但将其保留为空：/cloud-firestore-export?outputUriPrefix=gs://[my-project-name].appspot.com/backups&collections
3. IAM权限：向我的用户帐户 my-name@domain.com 添加 Cloud Datastore Import Export Admin 权限，因为这是电子邮件与gcloud config configurations list下的项目关联的帐户。

Answer 1

问题是 package.json 版本不能低于1.0.0。我正在尝试使用0.16.0。我正在将说明发送给文档团队，并且该文档应包含在文档中以节省人员时间。
