SessionMiddleware not available on Vercel

[edmbn]

What is the problem?

Using Vercel on production, on latest version of Blitz (0.42.4), I get an authentication error: "Sorry, we had an unexpected error. Please try again. - TypeError: Cannot read property '$create' of undefined".

Paste all your error logs here:

ERROR login() 
 TypeError  Cannot read property '$create' of undefined
error stack:
• login.js:68 <anonymous>
.next/serverless/pages/api/rpc/login.js:68:21

Paste all relevant code snippets here:

This is my blitz.config.ts (without next-translate worked fine):

import { BlitzConfig, sessionMiddleware, simpleRolesIsAuthorized } from "blitz"
const nextTranslate = require("next-translate")

const config: BlitzConfig = {
  i18n: {
    locales: ["es", "en"],
    defaultLocale: "en",
  },
  middleware: [
    sessionMiddleware({
      cookiePrefix: "hirin_app",
      sessionExpiryMinutes: MAX_AGE_IN_MINUTES,
      isAuthorized: simpleRolesIsAuthorized,
      publicDataKeysToSyncAcrossSessions: ["role", "profileId"],
    }),
  ],
}

module.exports = nextTranslate(config)

What are detailed steps to reproduce this?

1. Login and create a session when useTranslate is setup on blitz.config.ts while on Vercel production

Run blitz -v and paste the output here:

Was it working with next-translate with previous Blitz releases?

[edmbn]

I didn't try since I was using next-rosetta. Once I added the blitz.config.ts change with next-translate it started showing this error on production.

[beerose]

I think there's a bug related to wrapping the config — I noticed the same issue locally with a different library. In your case, does it also happen locally?

[edmbn]

With next-translate I can't reproduce it locally

[edmbn]

I can confirm it's only happening on Vercel in my case. On Render it is working fine.

[armandabric]

I confirm I have the same issue on Vercel, but not on render (I just give it a try)

I'm getting this after upgrading from 0.39.0 to 0.45.3.

[matthieuh]

I'm also confirming issue is still happening with version 0.45.3. Is there any workaround?

[matthieuh]

Sorry, but was is the status of this issue? This is not clear to me since this one is closed: #385

Is there anything I could do to help on this topic?
