Description

NOTE: if this is affecting anyone currently, downgrading to 0.469.0 solves it for me

From 0.470.0 using lucide-react icons breaks my react-router v7 deployments.

No problems building locally and serving with react-router serve, and no problem running react-router build for the deployment - no errors or warnings.

But visiting the page seems to crash the Netlify lambda itself (also tested on Vercel). Here is the error log from Netlify:

Jan 17, 01:20:06 PM: ERROR Uncaught Exception {"errorType":"Error","errorMessage":"EMFILE: too many open files, open '/var/task/node_modules/lucide-react/dist/esm/icons/message-circle.js'","code":"EMFILE","errno":-24,"syscall":"open","path":"/var/task/node_modules/lucide-react/dist/esm/icons/message-circle.js","stack":["Error: EMFILE: too many open files, open '/var/task/node_modules/lucide-react/dist/esm/icons/message-circle.js'"]}

Also note that this isn't a react v19 issue, it's happening on 18.3 as well

Steps to reproduce

Here's a minimal repro: https://github.com/rub1e/lucide-react-repro

It's just the Netlify React Router starter with one page with a single lucide icon

Here it is crashing on netlify: https://venerable-sunshine-738964.netlify.app/
