I'm not aware of any issues as long as you are on the latest Nuxt and nuxi versions, so it might be easier to help if you open an issue with a reproduction on https://github.com/nuxt/nuxt/issues.
Will do once I’ve investigated more. Tried bun yesterday evening and just saw this thread this morning while heading to the lake :)
Thank you for your awesome work on nuxt 3, by the way!
