Folder routes not working

[Muhammadinaam]

Reproduction

I created following structure:

app
  -routes 
     - index.tsx
     - signin.tsx

You can see the contents of the files in the image below.

I ran command npx remix routes. It is not recognizing signin route. When I try to open in browser, I get 404.
