Firebase定时函数未成功部署问题求助

严格遵循Firebase官方教程部署定时函数，但部署后找不到该函数。需求是让函数在指定时间触发，测试时设置为部署时间后几分钟，已启用所需GCP服务：App Engine App和PubSub。

解决方案 #

• 修正部署命令的函数名称：部署命令指定的functions:schedule-monthly与代码中导出的函数名scheduledFunction不匹配，正确命令应为：

  firebase deploy --only "functions:scheduledFunction"
  

• 确保函数文件被加载：Firebase Functions默认仅加载index.js，需在index.js中导入自定义函数文件：

  // index.js
  require('./schedule-monthly');
  

• 升级firebase-functions SDK：当前使用的3.15.4版本低于要求的≥3.20.0，执行命令升级：

  npm install --save firebase-functions@latest
  

• 重新部署：完成上述步骤后，执行正确的部署命令，再通过firebase functions:list验证是否部署成功。
