无法在GCP密码管理器中访问密码

我正在尝试将代码从使用.env文件中存储的API密钥迁移到使用Google Cloud Platform Secrets Manager。我已按照此处的说明进行操作，但遇到错误消息，说我无权访问该机密。

import * as admin from "firebase-admin"
import { SecretManagerServiceClient } from "@google-cloud/secret-manager"

admin.initializeApp()
const secretClient = new SecretManagerServiceClient()

async function main() {
  async function getSecret(): Promise<string | null | undefined> {
    const [version] = await secretClient.accessSecretVersion({ name: "TELEGRAM_TOKEN" })

    return version.payload?.data?.toString()
  }

  const TELEGRAM_TOKEN = await getSecret()
  console.log(TELEGRAM_TOKEN)
}

main().catch(console.error)

那就是我得到的错误：

> node lib/app.js --telegram

我确实创建了一个具有“所有者”权限的服务帐户，将其下载并制作了export GOOGLE_APPLICATION_CREDENTIALS=/Users/...。执行时，我的服务帐户.json文件位置正确显示echo $GOOGLE_APPLICATION_CREDENTIALS。

我真的不知道我在做什么错。
