Converting circular structure to JSON

I’m making an app with NuxtJs and after update Axios from 0.15.3 to 0.16.1, I got bellow error.

TypeError: Converting circular structure to JSON
    at Object.stringify (native)
    at serialize (/home/masoud/Sources/cynthia-mobile/node_modules/serialize-javascript/index.js:72:20)

---

• axios version: 0.16.1
• Environment: e.g.: node v6.10.0, chrome 57, ubuntu 16.04

const axios = require(‘axios’); const CircularJSON = require(‘circular-json’);

axios.get(url, config).then((response)=>{ let json = CircularJSON.stringify(response); res.send(json); }).catch((error)=>{ console.log(error); });

This worked for me!

This error will also occur if you are try to include the response from axios in your response as shown below. (res.json(response)😉 apiRouter.post( "/mtp/:email", jwt({ secret: process.env.SECRET }), (req, res) => { var host = "https://www.mountainproject.com"; var path = "/data/get-user?email=" + req.params.email + "&key=" + process.env.MTPKEY; var url = host + path; axios .get(url) .then(response => { res.json(response); }) .catch(err => { res.status(500).send(err); }); } );

Simple fix is to make sure you are referencing response.data res.json(response.data);
