Cannot serve production version of app

[joestrkr]

Current Behavior

When trying to serve a production version of my react app, I always get the warning about conflicting NODE_ENV values. This only happens with serve. Building the app works as expected for both dev and prod modes.

To make sure that it is not some configuration issue in my repo I created a fresh workspace with nx 14.1.4 and it is totally reproducible. The build is always running in development mode.

Expected Behavior

When I run serve in prod mode, the app should be built in prod mode.

Steps to Reproduce

Create a new workspace and try to serve the app in prod mode.

npx create-nx-workspace@latest test --preset=react --appName=demo

# Then serve
nx serve demo --prod
