getHeader is not a function when using Tanstack Form with Tanstack Start RC

Repro: https://stackblitz.com/edit/tanstack-form-tdx1ytd7?file=vite.config.ts Unfortunately a separate already reported error prevents the repro from running in stack blitz but can still download if needed. 
Server Fn Error!

As a side note, TanStack Start doesn't work in stack blitz. So all the reproductions/examples in the docs use CodeSandbox instead.

the linked PR should have more information. I saw some internal discussions about it, so the case is ongoing. Your best bet is to use the PR to track this
