Question

我已部署了Cloud Firebase功能来更新某些汇总数据，但我已经

aggregateReceivedRatings：错误：无法从Firestore值解码类型：{＆＃34; integerValue＆＃34;：＆＃34; 3＆＃34;} 在DocumentSnapshot._decodeValue（/user_code/node_modules/firebase-admin/node_modules/@google-cloud/firestore/src/document.js:464:15）在DocumentSnapshot.get（/user_code/node_modules/firebase-admin/node_modules/@google-cloud/firestore/src/document.js:372:17） at exports.aggregateReceivedRatings.functions.firestore.document.onWrite.event（/user_code/lib/index.js:9:32）在对象。（/user_code/node_modules/firebase-functions/lib/cloud-functions.js:59:27）在下一个（本地） at /user_code/node_modules/firebase-functions/lib/cloud-functions.js:28:71 在__awaiter（/user_code/node_modules/firebase-functions/lib/cloud-functions.js:24:12）在cloudFunction（/user_code/node_modules/firebase-functions/lib/cloud-functions.js:53:36）在/var/tmp/worker/worker.js:695:26 at process._tickDomainCallback（internal / process / next_tick.js：135：7）

该功能非常类似于Firestore解决方案部分中针对聚合查询所示的功能：

exports.aggregateReceivedRatings = functions.firestore.document('users/{userId}/feedbacks_received/{ratingId}')
.onWrite(event => {
  var ratingVal = event.data.get('rating');

  const db = admin.firestore();  
  var restRef = db.collection('users').document(event.params.userId);

  return db.transaction(transaction => {
    return transaction.get(restRef).then(restDoc => {
      var newNumRatings = restDoc.data('received_feedbacks').tot + 1;

      var newSum = restDoc.data('received_feedbacks').sum + ratingVal;

      return transaction.update(restRef, {
        sum: newSum,
        tot: newNumRatings
      });
    });
  });
});

评级值为整数3。

我也跑

npm install firebase-functions @ latest firebase-admin @ latest --save

并重新部署，但没有运气。

我的package.json包含以下内容：

    {
  "name": "functions",
  "scripts": {
    "build": "./node_modules/.bin/tslint -p tslint.json && ./node_modules/.bin/tsc",
    "serve": "npm run build && firebase serve --only functions",
    "shell": "npm run build && firebase experimental:functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "main": "lib/index.js",
  "dependencies": {
    "firebase-admin": "~5.4.2",
    "firebase-functions": "^0.7.1"
  },
  "devDependencies": {
    "tslint": "^5.8.0",
    "typescript": "^2.5.3"
  },
  "private": true
}

任何帮助？

只需将firebase admin更新为5.5.1。它对我有用。只需使用命令行： npm install --save firebase-admin@^5.5.1
