I can reproduce the issue in my main.ts if I use the same approach as you here: https://github.com/auth0/node-jwks-rsa/blob/master/src/wrappers/request.js#L6

That is, simply importing request from axios:

import { request } from "axios";
request({
  url: "https://www.google.be",
}).then(r => console.log(r));

Also fails with:

/home/sebastien/wks/didowi/node_modules/axios-cookiejar-support/lib/index.js:58
    const mergedConfig = mergeConfig(_defaults.default, mergeConfig(this.defaults, config));
                                                                         ^

If I instead do the following, then it works fine:

const axios = require('axios').default;

axios.request({
  url: "https://www.google.be",
}).then(r => console.log(r));

It seems related to be the (new?) idiomatic way to use Axios: https://github.com/axios/axios#note-commonjs-usage.
Don't ask me more, I'm not using Axios directly :)

I think that I've understood where this is coming from. In my app, I use nano, which has recently switched to Axios and has added cookie support through axios-cookiejar-support. Unfortunately, this causes side-effects.

I think that the axios-cookiejar-support library shouldn't crash and burn, so node-jwks-rsa wouldn't need to change. Meanwhile, it might be useful for this library to use the idiomatic way to use Axios so that app-specific customizations are taken into account.

@dsebastien thanks for the investigation and the PR. We want to move away from axios, and any specific request library, and instead use node internals, while allowing for consumers of the library to completely replace how the request is made with a fetcher option. I've raised a PR for it here #218

We could patch 1.x with your PR #216, but let me know if you find it necessary.

Good to know; it seems like a good move forward.

I'm stuck with this issue at the moment, so I've locally worked around the issue by modifying the code under node modules. If you could release a minor version with the PR that I've sent, it would be great & would allow me to move forward, while waiting for #218 to land and a larger release to come out.

Hello @davidpatrick , I had the same problem as dsebastien with the same environment and I am stuck. it will be great if i can have the patch for the suggested solution please.

Hey @houssembenarbia, I'll be releasing a new 1.x patch today. Thanks for raising
