Describe the Bug

Observed behavior

I have made a website with Nuxt 3 (v3.14.159) and when I try to run the website locally as CF Pages (also the same error on Cloudflare Pages own servers) I get the following error: [ERROR] service core:user:worker: Uncaught TypeError: Invalid URL string

The error log is not helpful for me as I am unable to locate and find out whats wrong.

Expected behavior

It should not give an error.

Steps to reproduce

I am not able to provide a public repo or minimal working code, but can provide the repo to the devs here. If no one else have any helpful advice.

This is how my wrangler.toml file looks like:

compatibility_date="2024-09-02"
compatibility_flags=["nodejs_compat_v2"]

Commands used to build and start the server:

"build:cf": "nuxi build --preset=cloudflare_pages",
"start:cf": "wrangler pages dev ./dist", 

Please provide a link to a minimal reproduction

No response

Please provide any relevant error logs

> wrangler pages dev ./dist

My hunch is that the issue is related to usage of new URL + import.meta.url in my code, since I had a similar issue when deploying the exact same code output to Netlify, which also uses esbuild and has a known issue with processing import.meta.url, and I understand that Wrangler is also using esbuild.

---

However, unlike Netlify, there seems to be no way to opt-out of bundling with esbuild that I can find, other than through the CLI and the --no-bundle flag, which I'm not using (just using the git integration + functions/ directory).

I would love to be able to do through wrangler.toml, but it seems like that is not supported - #6434 ? For example, with Netlify I can do this in their netlify.toml and nothing will get processed.

[build.processing]
  skip_processing = true

The same code works fine on Vercel using their Build Output API.

(I'm basically testing the same code sample across all hosting providers)
