将运行时更改为 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，该函数运行完全正常。但是，由于它很快将被弃用，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。详细信息：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);
    });
};

Answer 1

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”）

Answer 2

我遇到了同样的问题，似乎在以前的版本中我们不需要在环境变量中使用GCLOUD_PROJECT，即它会自动检测到它，但从节点10开始我们需要显式地传递它。我就是这样解决的。因此，不要对其进行硬编码，而是尝试在云函数环境变量中传递GCLOUD_PROJECT 。

注意：GCLOUD_PROJECT是项目 ID，而不是项目名称。
