unsupported key type when trying to import a key set

[kaihendry]

Imagine the following code:

"use strict";
const axios = require("axios");
const jose = require("node-jose");

async function working(url) {
  const jwksResponse = await axios.get(url);
  // do i need to iterate through the keys?
  return await jose.JWK.createKeyStore().add(jwksResponse.data.keys[0], "jwk");
}

async function notWorking(url) {
  const jwksResponse = await axios.get(url);
  return await jose.JWK.createKeyStore().add(jwksResponse.data, "jwk");
}

async function main() {
  const publicKeyStore = await working(
    "https://login.microsoftonline.com/common/discovery/v2.0/keys"
  );

  console.log(publicKeyStore);
  publicKeyStore = await notWorking(
    "https://login.microsoftonline.com/common/discovery/v2.0/keys"
  );
}

main();

My expectation was:

1. Maybe a convenience function to fetch the keys
2. A way for all the keys to be added without iterating through the retrieved keys

Am I missing something please?
