我正在尝试使用这里的说明设置我的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 new PathTemplate (/workspace/node_modules/google-gax/build/src/pathTemplate.js:55:54)

有什么调试建议吗？
我尝试查找权限中的错误。例如，虽然GCL运行正常，但我不知道如何检查服务是否有权访问特定存储桶。我还尝试查找脚本中的错误。index.js

const firestore = require('@google-cloud/firestore');
const client = new firestore.v1.FirestoreAdminClient();
// Replace BUCKET_NAME
const bucket = 'gs://EDITEDHERE.appspot.com'

exports.scheduledFirestoreExport = (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);
    });
};

和包. json

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