Question

我在这里关注本教程：Tutorial

一切似乎都可以，它使我可以完成教程中的所有操作，但是当我运行该函数时，会出现此错误。

Start()

textPayload: "TypeError: Cannot read property 'charCodeAt' of undefined

我看不出是什么问题。我按照教程中的要求更改了存储桶和应用ID。

我处于Blaze计划，可以使用shell命令并使用

将数据库手动导出到存储桶中

gcloud firestore导出gs：// bbbdata-backup

我正在使用Firebase网站上的GCP控制台并使用此代码。

insertId: "000000-8410c5c7-8304-42b6-b2b6-dd55a54e8cab"
resource: {2}
timestamp: "2020-07-11T18:14:35.981Z"
severity: "ERROR"
labels: {1}
logName: "projects/b-b-b-app/logs/cloudfunctions.googleapis.com%2Fcloud-functions"
trace: "projects/b-b-b-app/traces/d7c07a715d0106225d9963ce2a046489"
receiveTimestamp: "2020-07-11T18:14:44.813410062Z"
}

去年我遇到过类似的问题，可能您缺少一些许可，我会这样做，希望这对您有用：

import * as functions from 'firebase-functions'
import { auth } from 'google-auth-library'

export const generateBackup = async () => {
  const client = await auth.getClient({
    scopes: [
      'https://www.googleapis.com/auth/datastore',
      'https://www.googleapis.com/auth/cloud-platform'
    ]
  })

  const path = `YOUR_FOLDER_NAME_FOR_THE_BACKUP`
  const BUCKET_NAME = `YOUR_BUCKET_NAME_HERE`

  const projectId = await auth.getProjectId()
  const url = `https://firestore.googleapis.com/v1beta1/projects/${projectId}/databases/(default):exportDocuments`
  const backup_route = `gs://${BUCKET_NAME}/${path}`

  return client.request({
    url,
    method: 'POST',
    data: {
        outputUriPrefix: backup_route,
        // collectionsIds: [] // if you want to specify which collections to export, none means all
    }
  })
  .catch(async (e) => {
    return Promise.reject({ message: e.message })
  })

}

然后您可以确定这是此功能的触发器并相应执行。

注意：转到项目的IAM部分并找到App Engine服务帐户，您将需要添加角色Cloud Datastore Import Export Admin，否则，它将失败。

您可以阅读有关它的更多信息here，它非常详细。

干杯。
