Infinite repeating error message

[cfjedimaster]

Describe the bug

On OSX, trying to use ntl to run my Eleventy site, specifcally:

netlify dev -c "eleventy --serve --quiet"

I get this error in console repeated infinitely, and a huge amount of processes fired.

It isn't Eleventy as I can it just fine.

Steps to reproduce

Not really sure - this worked fine in WSL for years.

Configuration

I just updated to the latest ntl CLI package today.

Hello @cfjedimaster, thank you for reporting this.

Are there any error details above that?

I see you're using node 25.0.0. We officially only support LTS releases. Does this also occur on node 24?

I just tried 24 and confirms it happens there too. As far as I can tell, that's the only detail, it's repeated incredibly quickly and fills up my terminal so it's hard to tell.

Thank you for those details! Would you please be able to try it one more time with npx [email protected] dev -c "eleventy --serve --quiet" to check if this was introduced in 23.10.0? 🙏🏼 (or if that is also broken, feel free to try older versions as well, as that would be very helpful)

Thank you!

I can confirm that version does it as well. One thing to note, my site does load up, Eleventy runs and all that, so it must be something after.

I then tried @22, which loaded 22.4.0. But this died quickly with TypeError: Cannot read properties of undefined (reading 'prototype')
