Here is next.cofig.ts at sim/apps/sim

Context:
This app (dashboard) is inside a monorepo using [email protected]
The error occurs when upgrading dashboard from Next.js 15.3.3 to 15.4.1
Other apps within the same monorepo using previous versions of Next.js (15.2, 15.3) and turbopack activated are working correctly

I already tried removing the .turbo, .next and node_modules folders and rebuilding, but it's giving the same error.
