Hi, It seems my app is showing a error in preview mode. No changes have been made and production is still working from last successful deployment a few days ago. I go to preview via chat and this error is showsn Failed to load “clsx” from “clsx”, make sure it exists.

I assume you’re talking about v0. Are you still seeing the issue? Can you check your package.json dependencies? And make sure clsx is listed.

Hey @immy ! Just checking in to see if you’re still facing the “Failed to load clsx” issue in preview mode. Have you had a chance to look at your package.json dependencies? Excited to help if you need any assistance! Thanks for being part of the community!

Hi, Yes just checked and dependencies are listed and the otp login process also works in prod with new deployments. It’s only failing now in preview mode after v0 update.
