使用 Google Cloud Functions 设置 Firebase 自动备份时出错

Question

我正在尝试使用此处的说明设置我的 Firestore 的自动备份：https://firebase.google.com/docs/firestore/solutions/schedule-export

我得到错误：

TypeError: Cannot read properties of undefined (reading 'charCodeAt')
at peg$parsetemplate (/workspace/node_modules/google-gax/build/src/pathTemplateParser.js:304:17)
at Object.peg$parse [as parse] (/workspace/node_modules/google-gax/build/src/pathTemplateParser.js:633:18)
at new PathTemplate (/workspace/node_modules/google-gax/build/src/pathTemplate.js:55:54)

调试这个有什么建议吗？

我试过在我的权限中寻找错误。例如。我不知道如何检查服务是否可以访问特定的存储桶，尽管 GCL 运行正常。 我也试过寻找脚本中的错误。 索引.js

const firestore = require('@google-cloud/firestore');
const client = new firestore.v1.FirestoreAdminClient();
// Replace BUCKET_NAME
const bucket = 'gs://IWROTEMYBUCKETNAMEHERE'
exports.scheduledFirestoreBackup = (event, context) => {
  const databaseName = client.databasePath(
    process.env.GCLOUD_PROJECT,
    '(default)'
  );
return client
    .exportDocuments({
      name: databaseName,
      outputUriPrefix: bucket,
      // Leave collectionIds empty to export all collections
      // or define a list of collection IDs:
      // collectionIds: ['users', 'posts']
      collectionIds: [],
    })
    .then(responses => {
      const response = responses[0];
      console.log(`Operation Name: ${response['name']}`);
      return response;
    })
    .catch(err => {
      console.error(err);
    });
};

和 package.json

{
  "dependencies": {
    "@google-cloud/firestore": "^1.3.0"
  }
}
