Nextjs v15.1.6 module not found

[tarjelavik]

I have upgraded an older next.js site to the latest v15.1.6 version. I had many struggles with i18n and next-intl, but i think i maybe found a bug with clover-iiif.

I have no idea why, but i can document my recreation (https://github.com/tarjelavik/clover-iiif-debug):

npx create-next-app@latest clover-iiif-debug --use-npm
cd clover-iiif-debug
npm i next-intl @samvera/clover-iiif

I installed next-intl as i though that it messed up, but that seemed to not have any influence on the issue.

./node_modules/@samvera/clover-iiif/dist/index.mjs:6:1
Module not found: Can't resolve './helpers'

FIx

In the end downgrading next and react to v14 and v18 is a possible fix.

Investigated further. Changing the import solved it, x.default.

const Viewer = dynamic(
  // () => import("@samvera/clover-iiif").then((Clover) => Clover.Viewer), // works in Next v14, not in v15
  () => import("@samvera/clover-iiif/viewer").then((Clover) => Clover.default),
  {
    ssr: false,
  }
);

I guess something can be done to make it behave the same in v14 and v15, else an update to the docs could mention this difference?

Update: i see this already was discovered by @brogr: #234. Should have paid more attention to the other issues, sry.
