TypeError: Illegal invocation

[atmcalbt]

Overview

I've set up a basic API using Cloudflare Workers + Hono. When integrating the WorkOS Node.js library I'm seeing Unexpected error: TypeError: Illegal invocation when calling asynchronous WorkOS functions (such as userManagement.authenticateWithCode).

Example

type Bindings = {
  WORKOS_CLIENT_ID: string
  WORKOS_API_KEY: string
}

const app = new Hono<{ Bindings: Bindings }>()

app.get(
  '/callback',
  async (ctx) => {
    const workos = new WorkOS(ctx.env.WORKOS_API_KEY);

    const { accessToken, refreshToken } =
      await workos.userManagement.authenticateWithCode({
        code: ctx.var.code,
        clientId: ctx.env.WORKOS_CLIENT_ID
      })

    return ctx.body(null, 204)
  }
)

Extra

I'm using the latest version of the library (^7.11.3). I've tried to downgrade the version (down to 7.0.0) and I'm still seeing this. I'm also seeing this locally, not just remotely. Worth mentioning that code and clientId are strings.

My best guess is that this is related to Hono? I'm unsure how to fix it, so any guidance is much appreciated.

Quick update: downgrading the library to 6.8.0 did the trick. Note that the issue still persists on newer versions.

Hi @atmcalbt! I do developer education at WorkOS. And I ran into the same issue with v7 on Cloudflare Workers.

We don't have an immediate path forward on this but we're looking into what's causing the issue and hope to have a better solution (than downgrading) soon.

@chantastic any progress on this? I've just hit this issue too.

This is fixed in v7.19.0! Closing this for now, feel free to re-open if you're still running into issues.
