Updating to RC possibly broke deployment

[proud crag]

Repo: redacted
Netlify permalink to broken 404 link: https://68d329d2af81ec328595856a--hatchetbrand.netlify.app/

I migrated to createRouter() as per the guide.

Current deps

    "dev": "vite dev",
    "build": "vite build && tsc --noEmit",
    "start": "vite start"
  },
  "dependencies": {
    "@mdx-js/react": "^3.1.1",
    "@mdx-js/rollup": "^3.1.1",
    "@tanstack/react-router": "^1.132.2",
    "@tanstack/react-router-devtools": "^1.132.2",
    "@tanstack/react-start": "^1.132.2",
    "@types/mdx": "^2.0.13",
    "react": "^19.1.1",
    "react-dom": "^19.1.1",
    "rehype-pretty-code": "^0.14.1",
    "remark-frontmatter": "^5.0.0",
    "remark-gfm": "^4.0.1",
    "remark-mdx-frontmatter": "^5.2.0",
    "shiki": "^3.13.0",
    "zod": "^4.1.11"
  },
  "devDependencies": {
    "@csstools/postcss-global-data": "^3.1.0",
    "@netlify/vite-plugin-tanstack-start": "^1.0.0",
    "@shikijs/transformers": "^3.13.0",
    "@types/node": "^24.5.2",
    "@types/react": "^19.1.13",
    "@types/react-dom": "^19.1.9",
    "@vitejs/plugin-react": "^5.0.3",
    "postcss-preset-env": "^10.4.0",
    "typescript": "^5.9.2",
    "vite": "^7.1.7",
    "vite-tsconfig-paths": "^5.1.4"
  }

It deployed fine prior to RC, as if it cannot find the index.js file once built.
No build errors locally. Only the same warnings as seen on Netlify build log.
(Also gives me 404 on Vercel)

Likely something trivial as I see no one else seems to share this issue yet?

Also I did a test and deployed a fresh repo via the "Deploy to Netlify" button from Start Basic, and it also breaks into 404 the same way.

Thank you, it worked.
I already had it installed but not properly configured in vite.config, forgot to use netlify() in the plugin array. Also I had to set my Netlify env as legacy-peer-deps=true

I assume to make it work on Vercel its installing Nitro V2/V3 correct?

Has anyone run into Netlify Build w/ pnpm fails -- vite not found?

I've been banging my head against a wall for 2 hours now to get it to build correctly, but it isn't working:

[build]
  command = "pnpm build"
  publish = "dist/client"

[build.environment]
  PNPM_FLAGS = "--shamefully-hoist"

My package.json:

"scripts": {
    "dev": "vite dev --port 3000",
    "start": "vite --port 3000",
    "build": "vite build",
    "serve": "vite preview",
    "test": "vitest run",
    "lint": "eslint",
    "format": "prettier",
    "check": "prettier --write . && eslint --fix"
  },

and my vite.config:

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

const config = defineConfig({
  plugins: [
    // this is the plugin that enables path aliases
    viteTsConfigPaths({
      projects: ['./tsconfig.json'],
    }),
    tailwindcss(),
    tanstackStart(),
    netlify(),
    viteReact(),
  ],
})

export default config

and the build logs:

...
 > score-keeper@ build /opt/build/repo
3:58:55 PM: > vite build
3:58:55 PM: sh: 1: vite: not found
3:58:55 PM:  ELIFECYCLE  Command failed.
3:58:55 PM: ​
....

I found a solution, if a little hacky: the build command in the toml file should be:

[build]
  command = "pnpm build"
  publish = "dist/client"

[context.production]
  environment = {PNPM_FLAGS = "--shamefully-hoist"}

Thank you — I've sent this onto the Netlify engineering team to look into.
