Hydration errors only in dev mode

[oluijks]

I'm using Tanstack Start and on my home page I'm using the shadcn carousel, works fine but in dev mode It gives me hydration errors in the console. I fixed that by wrapping the component in a isClient state so the error is gone. I do wonder why there are no errors when I build the app? Perhaps someone could explain that for me?
