更新：底部添加了IAM设置的截图。
我已经尝试了以下方式但没有成功：
我在新项目中设置了Firebase Functions来运行一个express服务器，该服务器连接到PostgreSQL数据库并为API提供端点（以允许简单地从DebStroutData数据库读取记录）。
我已经授权了数据库，允许我的本地机器连接。在开发模式下它可以完美地工作。（我运行firebase serve来在本地模拟云功能。）
现在出现了问题 - 我无法在生产环境中连接到数据库。我知道原因是因为Firebase云函数实际上没有特定的IP地址，我无法在数据库中将这些IP地址列入白名单并允许连接。
所以，我已经尝试了以下步骤：
我已经将所有运行在Google中心区域的IP地址范围列入白名单：151.101.0.0/17（云函数运行在 https://[[remote-cloudfunctions-url]].cloudfunctions.net/app - 没有成功。
我尝试通过此文档 https://cloud.google.com/sql/docs/postgres/connect-functions 从Firebase内部连接到数据。这意味着创建一个服务帐户，提供适当的权限，并使用应用程序的内部实例名称作为主机："optivois-prod:us-east1:[[postgres-instance-connection-name]]"。但这里也没有成功。
以下是我的配置：
const Pool = require('pg').Pool
const pool = new Pool({
user: '[[db_user]]',
host: '/cloudsql/[[postgres-instance-connection-name]]/.s.PGSQL.5432',
database: '[[db_name]]',
password: '[[db_password]]'
})
- 我曾尝试为应用程序创建私有IP地址，但以另一种方式无法正常工作。
想知道是否有任何关于此问题的想法、思路或问题。
这是 Google Cloud IMA 成员的屏幕截图：
以下是错误堆栈（我已确保实例名称正确，并且具有访问数据库的权限）：
