Vercel builds not working after adding a workspace in root

Help
1

I have a folder called web, and currently in Vercel I have the root be pointed to web with the option to use files outside of directory. However, I tried setting up workspaces in the parent directly (main directory) and it works locally but getting a lot of issue when I build with node modules. The build is breaking on preview btw. Everything works however when I run it locally

{
  "name": "monorepo",
  "private": true,
  "workspaces": [
    "web",
    "packages/*"
  ],
  "scripts": {
    "dev": "yarn workspace something dev",
    "dev:local": "yarn workspace something dev:local",
    "dev:better-auth": "yarn workspace something dev:better-auth",
    "dev:preview": "yarn workspace something dev:preview",
    "build": "yarn workspace something build",
    "build:web": "yarn workspace something build",
    "lint": "yarn workspace something lint",
    "lint-fix": "yarn workspace something lint-fix",
    "test": "yarn workspace something test"
  },
  "engines": {
    "node": "=20"
  }
}

What errors do you see when it breaks?
