SvelteKit site builds locally, fails with Netlify, rollup import issue

Site: iil.is / iil-is.netlify.app

In one of my pages I am importing a BibTeX / .bib file which starts with @inproceedings{...:

import pubs from '../publications.bib?raw'

I am using Vite’s ?raw modifier as described here: Features | Vite

This builds fine locally but Netlify fails saying it can’t parse the file:

[rollup-plugin-dynamic-import-variables] Unexpected character '@' (2:0)

Why is Netlify behaving differently here? What can I do to get around this error?

I noticed that the package/repo Netlify is referring to:

Has actually been migrated elsewhere:

Does this imply Netlify is using an out of date package?

Hi @jarm,

Are you trying npm run build locally? Based on this issue:

The error doesn’t appear in dev but appears when you build for production.

Thanks!

I couldn’t find a workaround for this issue, so I moved the .bib to the static folder and I load it using fetch instead of import.
