Cannot read properties of undefined (reading 'name') issue when deployed to Vercel

[lidholm]

I'm trying to get the library working when deploying to Vercel. I have copied the minimal example and it seems to work fine when running it locally. But when deploying to Vercel it fails saying

This Edge Function has crashed.

Your connection is working correctly.

Vercel is working correctly.

500: INTERNAL_SERVER_ERROR
Code: EDGE_FUNCTION_INVOCATION_FAILED
ID: sfo1::tt25x-1733286729047-39138c735356

and the logs are showing

Since it is working locally but not when deployed, my best guess is that I have screwed up environment variables somehow, but not sure what.
I have some set through .env.production and some are set inside Vercel

Does the stacktrace tell you anything from here? Or do you have some tips on how I should continue debugging the issue?

Small update:
I tried debugging this more, and now think that maybe I had an issue with old cookies or something. After trying to remove code to find the issue and then adding it back, I now have the same code and it is working to log in (on the deployment from my branch).
I am still getting the same error in the logs though, which is a bit unfortunate since it is making it harder to look for other errors

Hey @lidholm!

Sorry for delayed response, I've been pretty busy in December

Could you run npx next info in the project directory and share the console output?

Since the error happens in next/dist/compiled/@edge-runtime, it might be related to specific Next.js version
