[Turbopack] Breaks @next/font/local

[kalm42]

What version of Turborepo are you using?

default for next 13

What package manager are you using / does the bug impact?

npm

What operating system are you using?

Mac

Describe the Bug

@next/font/local is broken with turbo. I get only an error from the @next/font library. "Error: @next/font/local failed to run or is incorrectly configured." I'm reporting it here because when I take off --turbo from the dev script everything works fine.

Expected Behavior

No error.

To Reproduce

• new install of next 13
• install dep @next/font
• add layout file
• import localFont from '@next/font/local'
• copy any font to same file location ./app/cool-font.woff
• Import the font as per instructions here
• add page file with any text just for testing purposes
• update package.json > scripts > dev: to use turbo
• run

Reproduction Repo

No response

Hey y'all, we're aware of this limitation. If you look very closely you'll see that we throw an error message about this support. We look forward to bringing support for this very soon!

https://github.com/vercel/turbo/blob/4c5cab2755444fd60aa91aaba798473e58de117b/crates/turbopack/src/lib.rs#L66-L67

#2545 and #2494 are both reporting the same thing. At this point it's not exactly a bug, more a known limitation, and internally we're tracking toward implementing it. @wbinnssmith is the person currently investigating it. 🔜

In the mean time this is a possible workaround to enable using fonts with Turbopack: https://nextjs.org/docs/messages/no-page-custom-font#possible-ways-to-fix-it
