Error: Docker build failed

To reproduce

  1. Create Nx monorepo with an app in, using pnpm
  2. Build the app with nixpacks build . --name myimagename -e NIXPACKS_NX_APP_NAME=appname
  3. Build fails with pnpm.cjs error

Expected behavior

Build works

Environment

macOS locally, and Railway.app build env

Workaround: override the build command with --build-cmd="pnpm nx run api:build:production --skip-nx-cache"

pnpx is broken in nixpacks, and also so is the nx cache if you don't include --skip-nx-cache too, the cache may fail the build due to some integrity issue
