This warning is important to make sure that you're not accidentally pulling in the large development builds in production. Are you seeing this warning in production?

Interested into the solution/explication about it too.
Using Shoelace 2.15 and 2.15.1 here, with Nuxt 3, integrated following this discussion : #1412

Not tried in production yet.

The warning should be appearing if you're not in production. The warning is there so that you don't unknowingly use the development build in production. If you try the app in a production build and still see the warning, then something's wrong.
