未与Cloud Functions和Firestore建立连接

Question

我在从云函数连接到我的firestore DB时遇到了问题。

我得到以下错误：

i  functions: Beginning execution of "test"

服务帐户凭据由GOOGLE_APPLICATION_CREDENTIALS环境变量指向。

这是我的函数代码：

const functions = require("firebase-functions");
const admin = require("firebase-admin");

admin.initializeApp();
let db = admin.firestore();

exports.test = functions.https.onRequest((req, res) => {

      db.collection("users").doc("test").set({
          'name': 'Michael'
      }).then(ref => {
          res.send(ref.id);
      })
      .catch(err => {
        console.error(err)  
        res.status(500).send(err);
      })

});

..。这些是我在package.json文件中的依赖项

"dependencies": {
    "firebase-admin": "^8.10.0",
    "firebase-functions": "^3.3.0"
  }

我看到有更多的人面临类似的问题，他们说我应该升级到最新版本的firebase-functions和firebase-admin，但在我的情况下，他们是最新的。我还删除了node_modules/并重新安装了它，但问题仍然存在。

有什么想法吗？

您是否设置过名为FIRESTORE_EMULATOR_HOST的环境变量

如果设置了该环境变量，则firebase admin SDK将尝试连接到仿真器，而不是连接到firestore，如果尚未启动仿真器，则会发生Error: 14 UNAVAILABLE: No connection established。https://firebase.google.com/docs/emulator-suite/connect_firestore?hl=en
