Next.js Application Does Not build When Upgrading to Next.js v16.3.2

[jtw-r]

Current Behavior

I cloned the nrwl/nextjs-template repo and upgraded Next.js to v16.3.2 (latest version as of writing this), because I was experiencing some build issues in my large work monorepo.

When running npx nx build @nextjs-template/web after upgrading Next.js, the process fails with a typescript error (TS6305). This did not happen on Next.js version ~16.2.11
