nitro: [Nitro/Unenv] cloudflare_pages build error: Could not resolve import string_decoder

Any solution to this? I am currently on firebase preset (with no error) and want to try cloudflare. Changing the preset to cloudflare-pages gives this error.

Hi. We are aware and this issue is under the track.

The issue is that you are using a library that is designed for Node.js and when trying to deploy to Cloudflare pages, Nitro (while trying to fix this with unenv) is not covering some subpath compatibility.

I should spend more time investigating what exact library is incompatible and a minimal (nitro only with only problematic dependency) could help to speed this up.

Was a solution ever found to @andrevandal’s problem? It seems like him and many others are experiencing the same issue with no luck.

Currently trying to build via the deployment guide for cloudflare and getting this exact same error. Any updates on this?

Same with KnexJS

[error] [nitro] Error: Cannot resolve "pg" from "/opt/buildhome/repo/node_modules/knex/lib/dialects/redshift/index.js" and externals are not allowed!

I got the exact same issue when importing firebase-admin inside a nitro plugin. But I figured out that it was the import that was incorrect. A minimal reproduction can be found at https://stackblitz.com/edit/github-znntty

The incorrect version was

import admin from 'firebase-admin';

export default defineNitroPlugin((nitro) => {
  const test = admin.initializeApp;
});

The errors disappeared after correcting the code to the following.

import { initializeApp } from 'firebase-admin/app';

export default defineNitroPlugin((nitro) => {
  const test = initializeApp;
});

I made this change but it didn’t work on my end, I’m still getting the same error “Cannot resolve “unenv/runtime/node/string_decoder/index/””

I’ve got the same error with “vercel-edge” Preset:
