next version 16.1.1 running into an issue with a monorepo here is my folder stucture ├── apps/ │ ├── web/ ← Next.js app goes here .next │ │ ├── src/

a lot of files removed due to private code the issue arise when i run install, the node_modules correctly appears in the root directory. this is my root package.json { "name": "code-snippets-monorepo", "version": "0.1.0", "private": true, "workspaces": [ "apps/", "packages/"

], "scripts": { "dev": "npm run dev --workspace=apps/web", "dev:worker": "npm run dev --workspace=apps/worker", "build": "npm run build --workspace=apps/web", "build:worker": "npm run build --workspace=apps/worker", "start": "npm run start --workspace=apps/web", "lint": "npm run lint --workspace=apps/web", "test": "npm run test --workspace=apps/web", "testW": "npm run testW --workspace=apps/web", "storybook": "npm run storybook --workspace=apps/web", "build-storybook": "npm run build-storybook --workspace=apps/web", "db:migrate": "npm run db:migrate --workspace=packages/database", "db:generate": "npm run db:generate --workspace=packages/database", "db:studio": "npm run db:studio --workspace=packages/database", "type-check": "npm run type-check --workspace=apps/web" }, "devDependencies": { "typescript": "^5", "tsx": "^4.21.0" } } then when i run npm run dev turbopack is infers the workspace incorrectly ERROR MESSAGE: Error: Next.js inferred your workspace root, but it may not be correct. We couldn't find the Next.js package (next/package.json) from the project directory: /home/jesse-collins/code-snippets/apps/web/app To fix this, set turbopack.root in your Next.js config, or ensure the Next.js package is resolvable from this directory. Note: For security and performance reasons, files outside of the project directory will not be compiled. See https://nextjs.org/docs/app/api-reference/config/next-config-js/turbopack#root-directory for more information.

npm error Lifecycle script dev failed with error: npm error code 1 npm error path /home/jesse-collins/code-snippets/apps/web npm error workspace @code-snippets/[email protected] npm error location /home/jesse-collins/code-snippets/apps/web npm error command failed npm error command sh -c next dev I attempted the fixes of clear cache rm -rf node_modules and package.lock.json. Also I obviously have my turbopack.root set I tried turbopack:{ root: path.join(__dirname, ".") }, turbopack:{ root: path.resolve(__dirname, ".") },

turbopack:{
  root:__dirname
},
turbopack:{
  root:'./'
},

Also attempted removing app out of src and having a basic app folder of just a layout and a page all depedencies are correct using react 19 "react": "19.2.0", "react-dom": "19.2.0" and node version 25.2.1

Current vs. Expected behavior

When running npm run dev --workspace=@code-snippets/web, I get the following error:

I expected Turbopack to find my package.jsonapp in my project root at web but it is instead looking in app

Additional context

I was running a single repo however have migrated to a monorepo also was using docker but the issue lies in that I can't even run it locally it should compile in theory and give a different error if there was compile error thanks for all your help!
