Thanks for the report, it looks like we need to be smarter and lazy load the correct adapter, as the pages router needs to import from next/navigation.js, and the app router from next/navigation, for some reason (see #368).

That or rework the pages router so that it doesn't use next/navigation at all (which was needed in v1 for compat, but now we can probably base it on top of next/router or something like that).

I tried reproducing the error in the e2e test bench, but I don't see any errors (see PR #878).

I thought I had moduleResolution set to bundler in the tsconfig.json, which might have made a difference, but it's set to node, like in FixMyBerlin/atlas-app (which I assume is the app you were trying to update).

In this case it was FixMyBerlin/trassenscout https://github.com/FixMyBerlin/trassenscout/blob/develop/tsconfig.json#L19 but that uses "moduleResolution": "node" as well.

@tordans & @rettgerst: There should be a fix for this issue in PR #917 (the pages router adapter now uses next/compat/router.js rather than next/navigation), would you be able to try the preview version?

@franky47 This error is still happening for me in v2.4.1:

unhandledRejection [Error: Cannot find module '/my-repo/node_modules/next/navigation' imported from /my-repo/node_modules/nuqs/dist/chunk-C3RNEY2H.js
Did you mean to import "next/navigation.js"?] {
  type: 'Error',
  code: 'ERR_MODULE_NOT_FOUND',
  url: 'file:///my-repo/node_modules/next/navigation'
}

I was able to resolve the issue with this patch (using patch-package):

@jdpnielsen thanks, can you try the following preview build (which is basically what your patch did) please?

pnpm add https://pkg.pr.new/nuqs@939
