TypeError: Right-hand side of 'instanceof' is not an object

[Desttro]

Hey. Hey,
I'm trying to send a test notification in my API, but I'm getting this error:

TypeError: Right-hand side of 'instanceof' is not an object

  message: Right-hand side of 'instanceof' is not an object
[mf:inf] POST /trpc/apple.sendTestNotification 200 OK (29ms)

I need to load a private key into a variable because my API server does not have a file system. And according to the types signingKey should be a string.

Here is my code (all variables are fictitious):

import {
  AppStoreServerAPIClient,
  Environment,
  SendTestNotificationResponse,
} from "@apple/app-store-server-library";

import { protectedProcedure, router } from "../trpc";

const issuerId = "37a80662-515d-11ee-be56-0242ac120002";
const keyId = "LN5NHPSU2D";
const bundleId = "com.mycompany.app";
const encodedKey = `-----BEGIN PRIVATE KEY-----
fazmQVRp7bRp3Mb5EzQcVRlOWZt7uaDo8RvgHCp7r6z7tyUyAEpN1vj7gEJHiOeY
XA3kRXAZYUQaoToDEOh00N128q9FAvz2tCu47cwXVXefhp2B6gT4v7XXMd2pBldM
T9GbWO6cXs4QVFxXQM1YGGBS9TfyMqDZTQ0gbviN7u6Yb6DcP9TGHB8QSDpMxzLy
v50IEodS
-----END PRIVATE KEY-----`;
const environment = Environment.SANDBOX;

const client = new AppStoreServerAPIClient(encodedKey, keyId, issuerId, bundleId, environment);

export const appleRouter = router({
  sendTestNotification: protectedProcedure.mutation(async () => {
    try {
      const response: SendTestNotificationResponse = await client.requestTestNotification();
      console.info(response);
    } catch (e) {
      console.error(e);
    }
  }),
});

Node.js: v18.17.1

I tried changing the formatting to:

const encodedKey = `-----BEGIN PRIVATE KEY-----fazmQVRp7bRp3Mb5EzQcVRlOWZt7uaDo8RvgHCp7r6z7tyUyAEpN1vj7gEJHiOeYXA3kRXAZYUQaoToDEOh00N128q9FAvz2tCu47cwXVXefhp2B6gT4v7XXMd2pBldMT9GbWO6cXs4QVFxXQM1YGGBS9TfyMqDZTQ0gbviN7u6Yb6DcP9TGHB8QSDpMxzLyv50IEodS-----END PRIVATE KEY-----`;

const encodedKey = `fazmQVRp7bRp3Mb5EzQcVRlOWZt7uaDo8RvgHCp7r6z7tyUyAEpN1vj7gEJHiOeYXA3kRXAZYUQaoToDEOh00N128q9FAvz2tCu47cwXVXefhp2B6gT4v7XXMd2pBldMT9GbWO6cXs4QVFxXQM1YGGBS9TfyMqDZTQ0gbviN7u6Yb6DcP9TGHB8QSDpMxzLyv50IEodS`;

None of that helped.

It could be related to auth0/node-jsonwebtoken#939

Cloudflare Workers not using Node.js. Maybe this will help cloudflare-worker-jwt

The Web Crypto API differs significantly from Node’s Crypto API. If you want to port JavaScript code that relies on Node’s Crypto API, you will need to adapt it to use Web Crypto primitives.

Consider using jose instead of jsonwebtoken

Not sure whether or not the following would fix this issue specifically, but for anyone wanting to provide the signing/private key from a variable/constant, it would need to be concatenated with \n. Example:

-----BEGIN PRIVATE KEY-----
fazmQVRp7bRp3Mb5EzQcVRlOWZt7uaDo8RvgHCp7r6z7tyUyAEpN1vj7gEJHiOeY
XA3kRXAZYUQaoToDEOh00N128q9FAvz2tCu47cwXVXefhp2B6gT4v7XXMd2pBldM
T9GbWO6cXs4QVFxXQM1YGGBS9TfyMqDZTQ0gbviN7u6Yb6DcP9TGHB8QSDpMxzLy
v50IEodS
-----END PRIVATE KEY-----

becomes

"-----BEGIN PRIVATE KEY-----\nfazmQVRp7bRp3Mb5EzQcVRlOWZt7uaDo8RvgHCp7r6z7tyUyAEpN1vj7gEJHiOeY\nXA3kRXAZYUQaoToDEOh00N128q9FAvz2tCu47cwXVXefhp2B6gT4v7XXMd2pBldM\nT9GbWO6cXs4QVFxXQM1YGGBS9TfyMqDZTQ0gbviN7u6Yb6DcP9TGHB8QSDpMxzLy\nv50IEodS\n-----END PRIVATE KEY-----"

Did anyone have any luck getting this to run in Cloudflare workers?
