next-on-pages build gives "Internal Server Error" on yarn pages:dev
Hi!
We have a NextJS app and trying to deploy to Cloudflare. On the yarn pages:build step, the following warnings/messages are displayed:
% yarn pages:build
yarn run v1.22.1
$ npx @cloudflare/next-on-pages
⚡️ @cloudflare/next-on-pages CLI v.1.8.2

The build completes successfully.
The dependency of Scheduler looks like this:
$ npm ls scheduler
<the-app>
└─┬ react-dom@18.2.0
└── scheduler@0.23.0
So this is an npm module used by standard react-dom.
Running with yarn pages:dev and launching localhost shows this only message in the browser:
Internal Server Error
And on the command-line this can be seen:
✘ [ERROR] ⨯ TypeError: (w.adapter || b.adapter) is not a function
wrangler:inf] GET / 500 Internal Server Error (178ms)
Not much to go on. There are references to generated files, like:
.../.vercel/output/static/_worker.js/next-on-pages-dist/webpack/86d03c243df5247d6f6729bd979a6117.js:62:138483)
But we assume this is related to the warnings/messages seen while building the application.
Has anyone seen something similar?
We appreciate hint and tips, as there seem to be little information available.
Kind regards,
/Peter
