The application works correctly when I run it locally, but if I try to dockerize it, I get a 500 fetch failed error with no logs. I also tried running the application with node --trace-warnings but no errors appear. The project is a pnpm monorepo, and the folder structure is

    package.json

Here is the apps/frontend/Dockerfile
