'Cannot get /' on a TanStack Start project in vite preview mode

[netimen]

Which project does this relate to?

Start

Describe the bug

I've create a Start project with pnpm create @tanstack/start@latest. I have not touched the code, I'm just installing the dependencies and launching the project. Dev version works ok, but when I try to build and preview the production build, I get Cannot GET /:

Your Example Website or App

I didn't change anything in the code

Steps to Reproduce the Bug or Issue

1. create the project pnpm create @tanstack/start@latest.

2. cd test
3. pnpm build && pnpm serve

4. go to localhost:4173 in the browser

Expected behavior

I expect to see the sample project, something like this (this is a screenshot from running the dev build):

Screenshots or Videos

No response

Platform

• Router / Start Version: 1.132.0
• OS: OS X 15.3.1 (24D70)
• Browser: Safari and a Chromium-based
• Browser Version: Safari 18.3
• Bundler: vite
• Bundler Version: 7.1.9

Additional context

I tried to launch the server manually node dist/server/server.js. It just quits immediately

[entrptaher]

issue persists even on the version 1.132.0 till 1.132.56;

For now, I've moved to nitro as alternative, but the default preview should work nonetheless.

What did you choose for options when you went through the app creation process?

Facing the same issue, these are the options I chose:

  Let's configure your TanStack Start application
│
◇  What would you like to name your project?
│  test
│
◇  Would you like to use Tailwind CSS?
│  Yes
│
◇  Select toolchain
│  Biome
│
◇  Select hosting provider
│  None
│
◇  What add-ons would you like for your project?
│  none
│
◇  Would you like any examples?
│  none
│
◇  Initialized git repository

[schiller-manuel]

we should probably remove "none" in the hosting section as it is confusing users

[jherr]

Fixed. There is no longer a none hosting option.

Any solution on this ?

[smashah]

are you lot using cloudflare?

if so try setting this at the top of your wrangler:

main = "@tanstack/react-start/server-entry"

[sujithx1]

im working one project it is same error Cannot GET / it has comming suddenly previous not showing
anyone can explain ?

[jherr]

Are you using pnpm dev or pnpm build and pnpm preview? Build and preview are about deployment, and you specifically did NOT want a deployment option. So that's why you are seeing issues on pnpm preview.

Beyond that, you are going to need to give us a lot more information than just Cannot GET /. Server logs (in text format) would be helpful.

[smashah]

This happened to me also. It happened when I updated from vite 6 to 7.

so i had to update my wrangler config to:

main = "@tanstack/react-start/server-entry"
compatibility_date = "2025-09-02"

and vite config to :

import tailwindcss from "@tailwindcss/vite";
import { defineConfig } from 'vite'
import { tanstackStart } from '@tanstack/react-start/plugin/vite'
import viteReact from '@vitejs/plugin-react'
import viteTsConfigPaths from 'vite-tsconfig-paths'
import { cloudflare } from '@cloudflare/vite-plugin'

export default defineConfig({
  server: {
    port: 9012,
  },
  define: {
    "process.platform": JSON.stringify(process.platform),
  },
  ssr: {
    noExternal: ["better-auth-harmony"],
  },
  plugins: [
    cloudflare({ viteEnvironment: { name: 'ssr' } }),
    // this is the plugin that enables path aliases
    viteTsConfigPaths({
      projects: ['./tsconfig.json'],
    }),
    tanstackStart(),
    viteReact(),
    tailwindcss({
      content: ["./src/**/*.{js,jsx,ts,tsx}"],
    }),
  ],
});

@jherr

This isn't user error, vite preview does not properly serve build artifacts. I tested with a bare bones basic SSR setup using the latest tanstack start version and its necessary peer dependencies.

I believe you. So you tested this https://github.com/TanStack/router/tree/main/examples/react/start-bare setup and vite preview didn't work there?
