Unable to access middleware before initialization

Hello I am trying to launch on vercel but i keep getting an issue using the latest version of tanstack I'm using router and tanstack start for server functionality and i keep getting the following error: [request error] [unhandled] [GET] https://tanstack-ume-ume-gih3m7v73-ume-projects.vercel.app/ ReferenceError: Cannot access 'dbMiddleware' before initialization To give more context in dbMiddleware. I define this inside of server/middleware/auth-middleware.ts

export const dbMiddleware = createMiddleware({ type: 'function' })
  .middleware([authMiddleware])

export const dbMiddleware = createMiddleware({ type: 'function' })
  .middleware([authMiddleware])

this is then used in server functions using the following:

export const createSetupIntent = createServerFn({
  method: 'POST',
})
  .middleware([dbMiddleware])

export const createSetupIntent = createServerFn({
  method: 'POST',
})
  .middleware([dbMiddleware])

I'm hoping somebody might be able to help me or has ran into a similar issue.

Hi manuel i actually figured it out, you can't call server functions from better auth lib haha

what do you mean?

Dang you responded fast, been busy over here i'm sorry. So i'm using better-auth and i was calling a server function from a hook within the library. This seemed to create a circular dependency. However i have even more issues with vercel now, i'm using MUI and it keeps giving me to many files open when trying to launch on vercel
