Пытаюсь протестировать мои облачные функции Firebase. Я следил за документацией и получаю следующую ошибку при запуске тестов. Я пробовал генерировать разные ключи, я попадаю в окно service key через Firebase, так что это правильный проект. Ошибка возникает при запуске тестов: npm test

 Error: Options object {"_fieldsProto":{"foo":{"stringValue":"bar"}},"_ref":{"_firestore":{"_settings":{"credentials":{"private_key":"KEY","client_email":"project@appspot.gserviceaccount.com"},"projectId":"project","firebaseVersion":"8.13.0","libName":"gccl","libVersion":"3.8.6 fire/8.13.0"},"_settingsFrozen":false,"_serializer":{"allowUndefined":false},"_projectId":"project","registeredListenersCount":0,"_lastSuccessfulRequest":0,"_backoffSettings":{"initialDelayMs":100,"maxDelayMs":60000,"backoffFactor":1.3},"_preferTransactions":false,"_clientPool":{"concurrentOperationLimit":100,"maxIdleClients":1,"activeClients":{},"terminated":false,"terminateDeferred":{"promise":{}}}},"_path":{"segments":["document","path"],"projectId":"project","databaseId":"(default)"},"_converter":{}},"_serializer":{"allowUndefined":false},"_readTime":{"_seconds":1602169684,"_nanoseconds":285000000},"_createTime":{"_seconds":1602169684,"_nanoseconds":285000000},"_updateTime":{"_seconds":1602169684,"_nanoseconds":285000000}} has invalid key "_fieldsProto"

const test = require('firebase-functions-test')({
     databaseURL: "####",
     storageBucket: "####",
     projectId: "#####",   }, './key.json');
 
 
const myFunctions = require('./index.js');
 
const wrapped = test.wrap(myFunctions.testFunction);
const snap = test.firestore.makeDocumentSnapshot({foo: 'bar'}, 'document/path'); 
wrapped(snap); 
test.cleanup();
  

Следуйте этой документации: https://firebase.google.com/docs/functions/unit-testing

Мой package.json:

 {
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "serve": "firebase emulators:start --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log",
    "test": "mocha --reporter spec index.test.js"
  },
  "engines": {
    "node": "10"
  },
  "main": "index.js",
  "dependencies": {
    "firebase-admin": "^8.10.0",
    "firebase-functions": "^3.6.1",
    "reportdatasummary": "file:reportdatasummary"
  },
  "devDependencies": {
    "firebase-functions-test": "^0.2.0",
    "mocha": "^8.1.3",
    "reportdatasummary": "file:reportdatasummary"
  },
  "private": true
}
  

В нем указан недопустимый ключ «_fieldProto», и если вы посмотрите, что на самом деле содержит этот dict:

 "fieldsProto":{"foo":{"stringValue":"bar"}}
  

Я думаю, что вам просто нужно удалить параметр, который вы передаете в свою обернутую функцию.

 const wrapped = test.wrap(myFunctions.testFunction);
wrapped(); 
test.cleanup();
