dev tool does not show source code

I used

 npm create cloudflare@latest remix-page -- --framework=remix

 npm create cloudflare@latest remix-page -- --framework=remix

npx remix build & npx pnpm run start

npx remix build & npx pnpm run start

. After opening dev tool using

, I don't see the application code (e.g.

routes/_index.tsx

routes/_index.tsx

). Any idea? Thanks.
