Nitro undefined preset/undefined emulation error

Hey
A side project that I'm working on has stopped working after upgrading Nitro to v2.12. I'm getting this error when I try to start the dev server:
 ERROR  Cannot start nuxt:  Nitro entry is missing! Is "undefined" preset correct?                                       
    at resolvePathOptions (node_modules/nitropack/dist/core/index.mjs:435:11)

    at async Object.run (node_modules/@nuxt/cli/dist/chunks/dev.mjs:135:43)

Possibly relevant is that the line right before the error says:
ℹ Using undefined emulation in development mode.

The project has nitro-cloudflare-dev installed, not sure if this may have anything to do with it.
I used Cloudflare's instructions (https://developers.cloudflare.com/workers/framework-guides/web-apps/more-web-frameworks/nuxt/) for setting up the project with their development tools preinstalled a few months back. I tried creating a new project to see if the error would repeat, but it didn't.

Any ideas what might be causing this to happen?
