keystone build error

[agloolik]

Hi,
I updated my keystone project to the latest version, it works in dev mode but when I try to build my project I get the following error on each of the static pages:
Generating static pages (0/36) [= ]Error: should not be imported outside of pages/_document.
This seems to be related not NextJs.
Has anyone experienced the same problem ?
Thanks,
Ivan

Looking at .keystone/admin/pages/index.js I get this:
export { HomePage as default } from '@keystone-6/core/___internal-do-not-use-will-break-in-patch/admin-ui/pages/HomePage';

I use yarn, adding :
"resolutions": {
"next": "13.4.12"
}
to package.json, deleting node_modules, and yarn lockfile, and reinstalling fixed everything.
