I'm getting this error when I try to create a USDZ.

The asset is a .jpg

Any idea why it does that sudently?

converted usd file extension from .usdz to .usdc: /var/app/current/tmp/e065a999d736e7fc6a161368fcab37b7b5b118de9d19f8c1c71b7407bfa2df69/usdz/dist.usdc

The image I'm using is this one

As you can see the EXIF says it is on a RGB channel.

I saw that you did an update on this file to force RGB for jpeg. Now it's working.
