Deployment at vercel not working (TS Start + Convex)

I'm trying to deploy an app on vercel with convex backend, better auth, and Tanstack Start. I followed all the rules (are just one) 
// vite.config.ts
import tailwindcss from "@tailwindcss/vite"
import { tanstackStart } from "@tanstack/react-start/plugin/vite"
import viteReact from "@vitejs/plugin-react"
import { defineConfig } from "vite"
import tsconfigPaths from "vite-tsconfig-paths"

export default defineConfig({
  plugins: [
    tsconfigPaths(),
    tailwindcss(),
    tanstackStart({ customViteReactPlugin: true }),
    viteReact()
  ]
})
// vite.config.ts
import tailwindcss from "@tailwindcss/vite"
import { tanstackStart } from "@tanstack/react-start/plugin/vite"
import viteReact from "@vitejs/plugin-react"
import { defineConfig } from "vite"
import tsconfigPaths from "vite-tsconfig-paths"

export default defineConfig({
  plugins: [
    tsconfigPaths(),
    tailwindcss(),
    tanstackStart({ customViteReactPlugin: true }),
    viteReact()
  ]
})

I was able to get this working using the docs / nitro v2. One other setting in vercel seems important. Framework Presets = "Other"
