Additional context

According to the error message, I believe that there is an issue parsing oklch values.

It might also be a resvg-js issue as satori render the image correctly in the OG image playground, but resvg-js fails to convert it in png.

this latest satori can convert it to svg and has that same effect with browser, but resvg-js cannot convert our svg to png. So I am afraid there are 2 issues:

1. next/image haven't use latest satori
2. resvg cannot handle oklch

Hello @samcx

While satori works, the problem seems to come from resvg-js, which might not fully support oklch. To resolve this, check your syntax and consider using a fallback color format like rgb or hsl, or update resvg-js if needed.
