Error: ENOENT: no such file or directory, open '/pages/index.tsx'

[HendrickSamuel]

I could not make it generate the route manifest.

• os: MacOS Monterey
• package manager: npm

Steps followed

1. npx create-next-app@latest
2. npm install delir --save-dev
3. add "generates-routes": "delir ./routes.ts" to package.json
4. run npm run generates-routes
5. error occurs

Error details

Start delir v0.0.1 - Generates a Route Manifest for you. It allows you to refer to a page by name instead of location
node:internal/process/promises:246
          triggerUncaughtException(err, true /* fromPromise */);
          ^

[Error: ENOENT: no such file or directory, open '/pages/index.tsx'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: '/pages/index.tsx'
}

What I tried:

• changing workspace entry
• using sudo
• installing delir globaly

What could cause this issue ?
