Hi Vercel Team,

I’m encountering a `500: INTERNAL_SERVER_ERROR` on my project:

> **Error: MIDDLEWARE_INVOCATION_FAILED**
> **ID:** `bom1::9t68q-1775668353488-ae3c8300d095` 

This happens when i was diploying 

I believe this might be an infrastructure issue, as:
- Everything works locally
- All environment variables are set correctly

Screenshot attached for reference.

Could you please help investigate?

Thank you
