Error: should not be imported outside of pages/_document.

Question

Im running a Next.JS application through Coolify and i've started getting this error but the commit that caused it only changed this

setBody('');
setTitle('');
setLabel('bug');
setOpen(false);

in an onSubmit handler and it all compiles fine locally and works in my dev environment but something makes it error on my server. And no there are no references to <Html> anywhere in the code. Repo is https://github.com/dinkelspiel/medialog
