Question

仅凭本教程Building A Telegram Bot With NodeJS，就可以按发布的方式进行操作。但是从终端

收到了此错误

    (node:20947) UnhandledPromiseRejectionWarning: TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'ClientRequest'
    |     property 'socket' -> object with constructor 'TLSSocket'

四处搜寻后，很多人遇到了它，但是我自己找不到解决方案。这是我的节点版本和npm信息。
节点v12.1.0和npm 6.9.0

vim package.json

{
  "name": "nodejs",
  "version": "1.0.0",
  "description": "", 
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },  
  "author": "", 
  "license": "ISC",
  "dependencies": {
    "axios": "^0.18.0",
    "body-parser": "^1.19.0",
    "express": "^4.16.4"
  }
}

先谢谢您。
