javascript - 将 Runtime 更改为 Node.js 10 后云功能失败

Question

我正在尝试通过云功能进行 Firebase 备份。当我使用 Runtime: Node.js 8 时，该函数运行得非常好。但是，由于它很快就会被弃用，我现在必须使用 Node.js 10。我的 fcloud 函数现在失败并出现以下错误:

错误:函数执行失败。细节:
无法读取未定义的属性“charCodeAt”

我的 index.js 如下:

const firestore = require('@google-cloud/firestore');
const client = new firestore.v1.FirestoreAdminClient();
// Replace BUCKET_NAME
const bucket = 'gs://gcp_firestore_ae2/firestore_export'
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: ['most_valuable_items','nric_img','pay_slip','pic_of_ofc_entrance'],
    })
    .then(responses => {
      const response = responses[0];
      console.log(`Operation Name: ${response['name']}`);
      return response;
    })
    .catch(err => {
      console.error(err);
    });
};

我遇到过同样的问题。我通过更改来修复它:
process.env.GCLOUD_PROJECT
到我的实际项目 ID(例如“my_app_37274”)
