A little more context:

7:50:19 AM [vite] Internal server error: `super()` is only valid inside a class constructor of a subclass. Maybe a typo in the method name ('constructor') or not extending another class? (831:8)

I suspect I have some bad setup coming from older Vinxi setup. So fixing that is likely my path forward. I’ll look into that shortly

Seems my problem was that I needed to upgrade to vite 7

Incase it helps anyone else I ran into this issue when upgrading better-auth which depends on @tanstack/react-start (dev dependency) To resolve the issue I updated vite to v7 and also updated my version of @tanstack/react-start and @tanstack/react-router
