typescript - 在一个简单的 Firebase 函数中将循环结构转换为 JSON

Question

错误信息：Error: function crashed. Details: Converting circular structure to JSON

尽管应该工作的微不足道的代码，我还是收到了错误。它似乎与 Firebase 模块有关。这是我的代码：

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
admin.initializeApp(functions.config().firebase);

export const addFxTransactionToFirestore = functions.https.onRequest(
    (req: any, res: any) => {
        console.log(req);
        res.send(req);
    }
);

我的 package.json 看起来像这样：

{
  "name": "functions",
  "scripts": {
    "lint": "tslint --project tsconfig.json",
    "build": "tsc",
    "serve": "npm run build && firebase serve --only functions",
    "shell": "npm run build && firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "10"
  },
  "main": "lib/index.js",
  "dependencies": {
    "firebase-admin": "^8.1.0",
    "firebase-functions": "^3.0.1"
  },
  "devDependencies": {
    "tslint": "^5.12.0",
    "typescript": "^3.2.2"
  },
  "private": true
}

我只是不明白为什么它不起作用，谷歌也没有解决我的问题。有线索的人吗？

编辑：JavaScript 编译的代码如下所示，以防万一：

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const functions = require("firebase-functions");
const admin = require("firebase-admin");
admin.initializeApp(functions.config().firebase);
exports.addFxTransactionToFirestore = functions.https.onRequest((req, res) => {
    console.log(req);
    res.send(req);
});
